Title: Diversity, Multiplexing, and PAPR Reduction Techniques for 5G Distributed MIMO Radio Access Network
Time: 10:00 - 10:30, Tuesday, February 19, 2019

Recently, the development of 5G mobile communications systems has been intensified to in order to start 5G services in around 2020. Significantly improving both the spectrum- and energy-efficiencies compared to 4G systems is demanded. One promising approach is an introduction of distributed MIMO radio access network (RAN), where a number of antennas are spatially deployed over a macro-cell area. A new frequency band, e.g. the mm wave band, where abundant bandwidth remains unused, will be utilized for enhanced mobile broadband (eMBB) services. Therefore, there will be a high Doppler shift problem and also a peak-to-average power ratio (PAPR) problem. In this talk, cooperative signal transmission techniques for 5G distributed MIMO RAN are presented, including diversity, multiplexing, and PAPR reduction, which are robust in a high Doppler shift environment. In distributed MIMO RAN, adjacent macro-cells are loosely connected, and hence, the inter-cell interference (ICI) problem will be produced. In this talk, adaptive ICI coordination (ICIC) is also presented.

Mohamed-Slim Alouini (IEEE Fellow)
Professor, University of Science and Technology (KAUST), Saudi Arabia

Title: Addressing spectrum scarcity through hybrid optical and radio-frequency wireless networks
Time: 15:00 - 15:30, Thursday, February 21, 2019

Rapid increase in the use of wireless services over the last two decades has led the problem of the radio-frequency (RF) spectrum exhaustion. More specifically, due to this RF spectrum scarcity, additional RF bandwidth allocation, as utilized in the recent past, is not anymore a viable solution to fulfill the demand for more wireless applications and higher data rates. The talk goes first over the potential offered by optical wireless (OW) communication systems to relieve spectrum scarcity. It then summarizes some of the challenges that need to be surpassed before such kind of systems can be deployed. Finally, the talk offers two recent studies illustrating how supplementing OW networks with RF backup access points increases these networks reliability and coverage while maintaing their high capacity.

Ender Ayanoglu (IEEE Fellow)
Professor, University of California, Irvine, USA

Title: Spatial Correlation in Single-Carrier Massive MIMO
Time: 16:00 - 16:30, Tuesday, February 19, 2019

In this talk, we present a single-carrier massive MIMO transmission system for the frequency selective Gaussian multi-user channel, in both uplink and downlink directions. We consider both cases of spatially uncorrelated and correlated channel and compare them in terms of the user achievable sumrate.

First, we consider a downlink channel. We develop a general expression for the achievable rate among users in the channel with and without correlation among antennas at the base station. It has been shown that, for the downlink channel, when there is no correlation between base station antennas or users, the Channel Matched Filter Precoder (CMFP) outperforms all the other precoders. In a highly-correlated massive MIMO downlink channel however, conventional CMFP does not perform as expected. We show the failure of CMFP in the presence of two different correlation patterns among antennas at the base station and suggest better precoding schemes which lead to a better achievable rate among users. We show that the suggested precoders outperform conventional CMFP. Second, considering the same groups of users and antennas, we develop a model for the uplink channel. Using two equalizer structures, we show the results of system performance in terms of achievable rate at the base station.

Associate Professor, Politecnico di Torino, Italy

Title: Vertical Service Deployment and Shifting in 5G Networks
Time: 10:30 - 11:00, Tuesday, February 19, 2019

It is common understanding that 5G networks are conceived for service deployment and support, not just for connectivity. In particular, automotive and e-health industries, as well as media content providers i.e., the so-called verticals, will request mobile operators to deploy services to be provided to mobile users. As part of the Service Level Agreement (SLA) between verticals and mobile operators, each service will be characterized by a set of requirements, both in terms of such high-level performance indices as reliability level, throughput, and latency, and in terms of networking, computational, and storage resources. It is up to the mobile operator to make decisions on how to deploy the vertical's services, which resources to use, and how to share them, depending on the load and the requirement to be met.

The talk will first highlight the main challenges to be addressed for an efficient deployment of vertical services in NFV-based 5G systems, putting particular emphasis on network slicing. It will then present possible optimizations and algorithms, and it will introduce the innovative concept of service shifting. The latter has been created to effectively cope with performance indices requirements and congestion conditions in the mobile operator's network. It consists in conceiving different versions of the same vertical service, each corresponding to a different amount of required resources for deployment and execution. To further clarify its benefits, the service shifting concept will be presented with reference to some real-world verticals' services.

Title:Managing QoS of Real-Time Interactive Applications Using Software-Defined Networking
Time: 16:30 - 17:00, Tuesday, February 19, 2019

We aim at leveraging the Software-Defined Networking (SDN) for dynamically managing the Quality of Service (QoS) demands of modern networked applications. Our approach is to provide the application developer with mechanisms for specifying and controlling application-level QoS metrics (e.g., response time or update rate), as an alternative to the traditional network-level metrics like latency, throughput, packet loss, etc. We study this problem for the challenging class of Real-Time Online Interactive Applications (ROIA) which include, e. g., multiplayer online games and simulation-based e-learning. Our contributions are as follows: 1) we develop and implement a Northbound API for specifying the application-level QoS requirements in ROIA, 2) we demonstrate how the application- level metrics “response time” and “update rate” can be automatically translated into network-level metrics understood by the SDN controller, and 3) we report experimental results on managing application-level QoS in an example online game on an OpenFlow-enabled testbed.

Title: Downlink and Uplink Non-Orthogonal Multiple Access in a Dense Wireless Network
Time: 17:00 - 17:30, Thursday, February 21, 2019

To address the ever increasing high data rate and connectivity requirements in the next generation 5G wireless network, novel radio access technologies (RATs) are actively explored to enhance the system spectral efficiency and connectivity. As a promising RAT for 5G cellular networks, non-orthogonal multiple access (NOMA) has attracted extensive research attentions. Compared with orthogonal multiple access (OMA) that has been widely applied in existing wireless communication systems, NOMA possesses the potential to further improve system spectral efficiency and connectivity capability. This talk focuses on the analytical frameworks for NOMA downlink and uplink multi-cell wireless systems that can be used to evaluate the system outage probability and average achievable rate. In the downlink NOMA system, two different NOMA group pairing schemes are considered, based on which theoretical results on outage and achievable data rates are derived. In the uplink NOMA, revised back-off power control scheme is applied and outage probability and per UE average achievable rate are derived. As wireless networks turn into more and more densely deployed, inter-cell interference has become a dominant capacity limiting factor but has not been addressed in most of the existing NOMA studies. In this paper a stochastic geometry approach is used to model a dense wireless system that supports NOMA on both uplink and downlink, based on which analytical results are derived either in pseudo-closed forms or succinct closed forms and are further validated by simulations. Numerical results demonstrate that NOMA can bring considerable system-wide performance gain compared to OMA on both uplink and downlink when properly designed.

Anders Høst-Madsen (IEEE Fellow)
Professor, University of Hawaii, USA

Title: Description Length for Machine Learning and Data Discovery
Time: 16:00 - 16:30, Wednesday, February 20, 2019

Information theory provides various methodologies for quantifying information in data; one of these is description length. Description length is the minimum number of bits needed to describe an object, e.g., an image, or a collection of data. The description length can reveal interesting properties of data, for example if two objects are related. Description length takes into account complexity of models, thereby avoiding finding spurious relationships.

In the talk we will discuss how to define and find descriptive length, focusing on specific applications: data discovery, anomaly detection, and hyperparameter selection in machine learning. We show that description length is optimum for anomaly detection as well as having other important theoretical properties. We further show how description length is related to generalization error in machine learning. This is then used for hyperparameter optimization in deep learning, such as choosing model order and regularization parameters.

Traditionally, information theory has been used for communications. This talk shows that information theory is also a useful tool for data science.

Marwan Krunz (IEEE Fellow)

Title: Network Discovery and Tracking in Directional Millimeter-Wave 5G Systems
Time: 16:00 - 16:30, Wednesday, February 20, 2019

5G+ wireless systems are expected to operate over millimeter-wave (mmW) spectrum, where communications are intrinsically directional and channels exhibit low (clustered) scattering with limited NLOS paths. At such frequencies, the base station (BS) needs to discover devices that enter its range and track them as they move within the BS range. The initial access and device/network discovery process must be performed within a strict time interval, often under unpredictable mobility. Tracking already discovered devices is yet another challenge, especially when sudden changes in the environment leads to disrupting the ongoing communications. Even at pedestrian speeds, significant beam misalignments and outage can occur. At higher speeds (e.g., drones, connected vehicles), beam misalignment can lead to disastrous outcomes. This talk will first discuss the challenges associated with device discovery and tracking in mmW-based 5G systems in highly mobile scenarios. Several potential solutions will then be presented and their limitations as well as complexity/performance tradeoff will be contrasted. Results from experimental mmW systems that use planar antenna arrays will be provided to showcase the potential of some of the proposed solutions.

Title: Use MU-MIMO at your own risk — Why we don’t get Gb/s Wi-Fi
Time: 16:30 - 17:00, Wednesday, February 20, 2019

With the ever growing popularity of mobile devices, the demand for wireless bandwidth has also increased, with the mobile users now expecting wireless network quality similar to what they experience with wired networks. Wireless LANs have evolved over the last twenty years, with major breakthrough technologies such as OFDM (Orthogonal Frequency Division Multiplexing), MIMO (Multiple Input Multiple Output), and MU (Multi-User)-MIMO. The latest IEEE 802.11ac standard supports up to 6.9 Gb/s theoretical capacity, but it could only be achieved with 8-streams in a “perfect” environment. Commercial 802.11ac wave-2 APs that include MU-MIMO capability, have only recently been made available in the market. We deployed a few APs from different vendors (that uses chipsets from different vendors) in various office environments and measured user throughput on smartphone mobile devices. We observe an enormous gap between theory and practice, with MU-MIMO often providing less throughput than SU (Single User)-MIMO in various network environments. We analyze the root cause of performance issues and suggest future research directions to achieve Gb/s Wi-Fi in practical deployments.

Advances in information and communications technologies have fueled a plethora of innovations in networking, caching, and computing, which are called upon to work together to enable better and more efficient services. In the area of networking, software-defined networking (SDN) has attracted great interests from both academia and industry. Another new technology called information-centric networking (ICN) has been extensively studied in recent years. As a new paradigm in computing, fog/edge computing has been proposed to deploy computing resources closer to end devices. In this talk, we will present an integrated framework that can enable dynamic orchestration of networking, caching and computing resources to improve the end-to-end system performance. As the complexity of the system is very high, we further present a big data deep reinforcement learning approach. Future research challenges will be discussed as well.

Title: Trust and Privacy of Deep Learning in Adversarial Settings
Time: 17:30 - 18:00, Tuesday, February 19, 2019

We are entering an exciting era where human intelligence is being enhanced by machine intelligence through big data fueled artificial intelligence (AI) and machine learning (ML). However, recent work shows that prediction models trained privately are vulnerable to adversarial examples and privacy invasion, both of which turn AI and ML against itself through inference attacks and both maliciously manipulate the prediction outputs with only a black box access to a machine learning as a service API. We argue that the trustworthiness should be an essential and mandatory component of a deep learning system for algorithmic decision making. This includes (1) the understanding and the measurement of the level of trust and/or distrust that we place on a deep learning algorithm to perform reliably and truthfully, and (2) the development of formal metrics to formally and quantitatively evaluate and measure the trust level of an algorithmic decision making result by examining the trustworthiness of the algorithm with respect of intentional and unintentional effects of execution, in the presence of different adversarial settings. In this talk, I will share some of our empirical results and characterization on trust and privacy of deep learning in adversarial settings.

Title: Toward a unified framework for wireless network slicing
Time: 17:00 - 17:30, Tuesday, February 19, 2019

The notions of softwarization and virtualization of the radio access network (RAN) of next-generation (5G) wireless systems are ushering in a vision where applications and services are physically decoupled from devices and network infrastructure. This crucial aspect will ultimately enable the dynamic deployment of heterogeneous services by different network operators over the same physical infrastructure. In this talk, we discuss a mathematical framework to formalize the RAN slicing and the RAN slicing enforcement problem and demonstrate their NP-hardness, as well as design and evaluate experimentally approximation algorithms that render the solution scalable as the problems increases in size.

Title: Progress in speech and audio coding technologies
Time: 16:30 - 17:00, Wesnesday, February 20, 2019

Progress in speech and audio coding technologies over 50 years is reviewed and the latest standardized coding schemes are introduced. Low rate speech coding schemes for mobile phones are commonly based on time domain LPC (Linear Predictive Coding). In contrast, audio coding schemes, which allow longer coding delay for broadcasting, portable player and storage applications, have been based on frequency domain compression technologies. Recently, however, LPC has come to be commonly used for all types of coding schemes, because of various market needs, such as a low bitrate and unified speech and audio coding, and lossless coding. In line with this trend, two new standardized coding schemes are introduced. One is a simple and flexible audio lossless coding standard, MPEG-4 ALS (Audio Lossless) for high quality digital broadcasting and delivery. The other is a low bit rate and super wide band speech and audio coding standard, 3GPP EVS (Enhanced Voice Services) for VoLTE (Voice over LTE).

Takehiro Moriya received the B.S., M.S., and Ph.D. degrees in mathematical engineering and instrumentation physics from the University of Tokyo, in 1978, 1980, and 1989, respectively. Since joining NTT laboratories in 1980, he has been engaged in research on medium to low bit rate speech and audio coding. In 1989, he worked at AT&T Bell Laboratories as a Visiting Researcher. Since 1990 he has contributed to the standardization of coding schemes for the Japanese cellular phone, ITU-T, ISO/IEC MPEG, and 3GPP. His many inventions include the pitch synchronous innovation scheme and the conjugate vector quantization. Both have been adopted to PSI-CELP (Pitch Synchronous Innovation Code Excited LP) in the Half-rate Japanese Public Digital Cellular phone standard and to CS-ACELP (Conjugate Structure Algebraic CELP) in ITU-T G.729 standard. His team also made a principal leadership in establishing MPEG audio lossless coding (ALS), and contributed to establish 3GPP EVS.

He is a member of the Speech and Language processing Technical Committee of the IEEE Signal Processing Society.

Title: BRACELET: Edge-Cloud Microservice Infrastructure for Aging Scientific Instruments
Time: 16:30 - 17:00, Thursday, February 21, 2019

Recent advances in cyber-infrastructure have enabled digital data sharing and ubiquitous network connectivity between scientific instruments and cloud-based storage infrastructure for uploading, storing, curating, and correlating of large amounts of materials and semiconductor fabrication data and metadata. However, there is still a significant number of scientific instruments running on old operating systems that are taken offline and cannot connect to the cloud infrastructure, due to security and network performance concerns. In this talk, we discuss BRACELET - an edge-cloud infrastructure that augments the existing cloud-based infrastructure with edge devices and helps to tackle the unique performance&security challenges that scientific instruments face when they are connected to the cloud through public network. With BRACELET, we put a networked edge device, called cloudlet, in between the scientific instruments and the cloud as the middle tier of a three-tier hierarchy. The cloudlet will shape and protect the data traffic from scientific instruments to the cloud, and will play a foundational role in keeping the instruments connected throughout its lifetime, and continuously providing the otherwise missing performance and security features for the instrument as its operating system ages.

Title: Person-Centric Multimedia Computing: Technology Inspirations Drawn from Needs of Individuals with Disabilities with Impacts to the Broader Population
Time: 13:30 - 14:00, Thursday, February 21, 2019

The era of ubiquitous computing has yielded technology that is highly aware of the unique attributes of its users. However, while the Human-Centered Multimedia Computing (HCMC) paradigm can capture these attributes among broad populations, interpersonal and intrapersonal variations call for a more modern approach, particularly in the realm of disability wherein these variations can have tremendous impact on the user experience. The Person-Centric Multimedia Computing (PCMC) paradigm is a novel approach to human-computer interaction in which technology is shaped from the ground up to account for the explicit needs, challenges, and attributes of an individual while utilizing adaptive techniques to maintain applicability among the broader population. As proofs of concept for PCMC in real person-centric problem domains, two example applications are considered: the Social Interaction Assistant, an assistive technology aimed at enhancing social interactions for individuals with blindness and visual impairment; and the Autonomous Training Assistant, a training tool which utilizes serious games and automated assessment to assist with at-home upper-extremity rehabilitation.

Title: An in-depth look at light field technology – compression and access of information
Time: 14:00 - 14:30, Thursday, February 21, 2019

Light Field (LF) Technology is the latest emerging innovation in digital media, seeing as an “upgrade” to the way optical devices take in light, with the potential to revolutionize the way we view and deliver real-life while promising more realistic Virtual and Augmented Reality applications. In contrast with a conventional camera, which records only light intensity, LF includes the intensity of light in a scene and the direction that the light rays are traveling in space, with every pixel having color and directional properties and its exact placement in space. The result is a plethora of captured information with excessive storage, bandwidth and processing requirements. Considering LF technology benefits come with an exponential increase in the amount of data required as well as the complexity of view access, the need for efficient compression and acceptable random access performance is essential. We will discuss the challenges in designing capturing schemes for light field content and the compression schemes for light field content that address the processing and access requirements for different applications.

Title: Communication Networks Design: Model-Based, Data-Driven, or Both?
Time: 17:30 - 18:00, Tuesday, February 19, 2019

Recently, deep learning has received significant attention as a technique to design and optimize wireless communication systems and networks. The usual approach to use deep learning consists of acquiring large amount of empirical data about the system behavior and employ it for performance optimization (data-driven approach). We believe, however, that the application of deep learning to communication networks design and optimization offers more possibilities. As opposed to other fields of science, such as image classification and speech recognition, mathematical models for communication networks optimization are very often available, even though they may be simplified and inaccurate. We believe that this a priori expert knowledge, which has been acquired over decades of intense research, cannot be dismissed and ignored. In the present work, in particular, we put forth a new approach that capitalizes on the availability of (possibly simplified or inaccurate) theoretical models, in order to reduce the amount of empirical data to use and the complexity of training artificial neural networks (ANNs). We concretely show, with the aid of some examples, that synergistically combining prior expert knowledge based on analytical models and data-driven methods constitutes a suitable approach towards the design and optimization of communication systems and networks with the aid of deep learning based on ANNs.

Title: From Millimeter-Wave to Quantum Communication: A Call for Cross-Disciplinary Research and Technology Innovation
Time: 17:30 - 18:00, Wednesday, February 20, 2019

Information science and technology is experiencing an explosive growth and unprecedented changes. On the one hand are the synergistic developments in optical and wireless communication networks and the proliferation of mobile and cloud computing. These developments are spawning new applications, including the Internet of Things, augmented and virtual reality, and autonomous vehicles, and imposing progressively stringent requirements on communication networks in terms of rate, latency, reliability and security. While innovations in communication and computing technologies will continue to advance information networks in the future, there is a growing sense that we are beginning to hit fundamental physical limits; e.g., the electromagnetic degrees of freedom for communication, and the density of integrated circuits for computation. On the other hand, a second information revolution is unfolding in parallel for exploiting fundamental quantum mechanical phenomena, e.g., “superposition” and “entanglement”, to manipulate information in ways that is not possible with existing “classical” technologies. The frontier of quantum information science and engineering promises to augment existing technologies and lead to radically new and disruptive paradigms for computing, communication and sensing. In this talk, I will highlight a few salient attributes that are shared by the emerging classical, quantum and hybrid information technologies and need to be exploited for fully harnessing their potential: i) cross-disciplinary research, ii) optical and photonic principles, techniques and technologies, iii) experimental testbed development, and iv) machine learning and artificial intelligence techniques.

Hearable devices: new directions with new functions:
Time: 16:00 - 16:30, Thursday, February 21, 2019

This talk presents new directions of hearable devices with new functions, namely personal authentication, inner-ear microphone, and an interface with new services. Personal authentication is performed by analyzing a reflection from the ear canal which exhibits different characteristics for each individual. An equal error rate of 0.97% is achieved with twelve feature components with a single second signal emission. An inaudible signal may be emitted in the ear for the comfort of the user. Inner-ear microphone is a promising replacement of standard microphones. The hearable device can be used for both an output and an input device which is more robust to environmental noise than ordinary microphones. For enhanced quality of the input signal, an adaptive noise canceller may be combined in adverse environments. Hearable devices can also accommodate a new signal processing function to replace the background signal. Such a function is useful for virtual/augmented reality (VR/AR) applications. Implementation of a personal authentications system on a smartphone and an inner-ear microphone on a DSP chip complement this talk.

Title: Machine Learning Radio Resource Management for Future Mobile Networks
Time: 17:00 - 17:30, Tuesday, February 19, 2019

We are witnessing the transition into the fifth generation (5G) cellular mobile systems. Is there any need for beyond 5G? A significant change in recent wireless networks is that much more data are collected from various sources, including channels, locations, radio access options, and network states. The availability of this large amount and various types of data can potentially transform the current knowledge-driven mobile network into a more powerful data-driven cognitive and learning-assisted mobile network. In this talk, we discuss how these learning algorithms can address the performance issues of high-capacity ultra-dense small cells in an environment with dynamical traffic patterns and time-varying channel conditions.

First, we introduce a bi-adaptive self-organizing network (Bi-SON) to exploit the power of data-driven resource management in ultra-dense small cells (UDSC). On top of the Bi-SON framework, we propose a polynomial regression supervised learning, and an affinity propagation unsupervised learning algorithm to improve energy efficiency and reduce interference of the operator deployed and the plug-and-play small cells, respectively. Finally, we discuss the opportunities and challenges of reinforcement learning and deep reinforcement learning (DRL) in more decentralized, ad-hoc, and autonomous modern networks, such as Internet of things (IoT), vehicle-to-vehicle networks, and unmanned aerial vehicle (UAV) networks.

Title: Learning to Appreciate: Transforming Multimedia Communications via Deep Video Analytics
Time: 17:30 - 18:00, Thursday, February 21, 2019

Media-rich applications will continue to dominate mobile data traffic with an exponential growth, as predicted by Cisco Video Index. The improved quality of experience (QoE) for the video consumers plays an important role in shaping this growth. However, most of the existing approaches in improving video QoE are system-centric and model-based, in that they tend to derive insights from system parameters (e.g., bandwidth, buffer time, etc) and propose various mathematical models to predict QoE scores (e.g., mean opinion score, etc). In this talk, we will share our latest work in developing a unified and scalable framework to transform multimedia communications via deep video analytics. Specifically, our framework consists two main components. One is a deep-learning based QoE prediction algorithm, by combining multi-modal data inputs to provide a more accurate assessment of QoE in real-time manner. The other is a model-free QoE optimization paradigm built upon deep reinforcement learning algorithm. Our preliminary results verify the effectiveness of our proposed framework. We believe that the hybrid approach of multimedia communications and computing would fundamentally transform how we optimization multimedia communications system design and operations.

Title: The Visual Communication over Wireless Networks
Time: 15:00 - 15:30, Thursday, February 21, 2019

The tradition radio access network is built on the specific hardware platform, now is evolving towards cloud computing platform. With the new mobile edge computing (MEC) architecture, the communication and computation is converging, which brings many new opportunities and challenges for visual communication. The introduction of edge cache can reduce unnecessary traffic load and improve latency in the wireless access networks. How to optimize the caching strategy which aims to maximize the successful transmission probability (STP) of the video contents at edge base stations (BSs) is an interesting problems. We try to develop a gradient based iterative algorithm to solve the general random caching strategy optimization problem. Furthermore, the visual communication produces big data traffics. It puts forward a huge challenge to the wireless networks, while its abundant information provides potential to improve the spectrum efficiency significantly. We investigate a novel data assisted communication of mobile image scheme, which utilizes a large amount of correlated (similar) images stored in the cloud to improve the spectrum efficiency and visual quality.

Autonomous driving vehicle control by edge computer network has been proposed. Each vehicle has a agent program on the edge and automatically moved to adjacent edge computer following to the vehicle. Each agent of the vehicle are communicated each-other in the cyber network. Then we can realize fairness as well as priority control among the vehicle.

Title: Machine Learning at the Edge: A Data-Driven Architecture with Applications to 5G Cellular Networks
Time: 17:00 - 17:30, Wesnesday, February 20, 2019

The fifth generation of cellular networks (5G) will rely on edge cloud deployments to satisfy the ultra-low latency demand of future applications. In this talk, we argue that an edge-based deployment can also be used as an enabler of advanced Machine Learning (ML) applications in cellular networks, thanks to the balance it strikes between a completely distributed and a centralized approach. First, we will present an edge-controller-based architecture for cellular networks. Second, by using real data from hundreds of base stations of a major U.S. national operator, we will provide insights on how to dynamically cluster the base stations under the domain of each controller. Third, we will describe how these controllers can be used to run ML algorithms to predict the number of users, and a use case in which these predictions are used by a higher-layer application to route vehicular traffic according to network Key Performance Indicators (KPIs). We show that prediction accuracy improves when based on machine learning algorithms that exploit the controllers’ view with respect to when it is based only on the local data of each single base station.
