Talk title: Tractable Analysis of Large-scale Multi-antenna Wireless Networks via Stochastic Geometry


Abstract

To accommodate the ever-increasing mobile data traffic and support enhanced mobile broadband services, there is a tremendous demand in boosting the capacity of wireless networks. One promising way is to exploit the spatial domain resources by deploying more antennas at transceivers, especially at the base station. Another effective approach is via network densification, which can significantly improve the area spectral efficiency. Therefore, multi-antenna networking forms a foundation for next-generation wireless networks. It is thus of significant practical importance to understand the performance of such complicated networks. While simulations can demonstrate many superior features of multi-antenna networks, mathematical analysis is essential to help expose their salient properties and provide effective design mechanisms without building and running complex system-level simulations. The aim of this tutorial is to present a unified analytical framework for tractable analysis of large-scale multi-antenna wireless networks via stochastic geometry. Compared with existing methods, this framework leads to more tractable expressions and makes the analysis of multi-antenna networks comparable to that of the single-antenna counterpart. Various application examples with different multi-antenna network models will be presented to illustrate the effectiveness of this analytical framework.

Talk title: Game-theoretic Methods for Modeling and Defending against Advanced Persistent Threats in Wireless Systems


Abstract

Advanced persistent threats (APTs) are a major threat to cyber-security, causing significant financial and privacy losses each year. Wireless systems and devices such as smartphones, laptops, and base stations are all vulnerable to APTs, as APT attackers launch multiple types of attack methods to steal information from these systems without being detected over a long period. In this tutorial, we introduce game-theoretic models to understand the behavior of the APT, assess cyber risks, and develop defense mechanism. The tutorial first gives an overview of game theoretic methods for cyber security and then focuses on several classes of static and dynamic game frameworks including Colonel Blotto games, multi-stage dynamic games, signaling games, and large-scale games. The tutorial also discusses prospect theory to model the risk-seeking and risk-aversion behaviors of the players and explain the deviations of their decisions from the expected utility-based results. We will also present computational and learning algorithms that can be implemented to improve the security and resilience of the cyber systems against APTs. The discussions will include the approximate dynamic programming approaches, hotbooting deep Q-network (DQN)-based schemes, and nonparametric statistical tools.

Talk title: Delay and Throughput Optimality in Cache Networks with Arbitrary Topologies


Abstract

Networks of caches naturally arise in many networking applications involving the distribution of content, including information centric networks (ICNs), content distribution networks (CDNs), and wireless edge networks, to name a few. Though, e.g., secondary-memory caches are well-studied, in contrast, the study of networks of caches still poses significant challenges. First, there exists an inherent computational challenge: this is precisely because of the combinatorial nature of content placement problems, many of which are NP-hard. Second, closed form solutions of quantities of interest (as, e.g., expected delay, hit/miss rates) become hard to obtain in multi-hop settings: even if arriving traffic in an LRU cache is, e.g., Poisson, the outgoing traffic may be hard to describe analytically. In this tutorial, we review several recently developed frameworks for the optimal design of cache networks under arbitrary multi-hop topologies. Well grounded in the theory of stochastic control, optimization, and distributed systems, these frameworks yield new algorithms for the joint optimization of forwarding, caching, scheduling, and congestion control in cache networks. Most importantly, these frameworks address both the combinatorial challenge related to caching, as well as modeling issues that arise due to the multi-hop nature of cache networks, for arbitrary topologies. We will review approximation algorithms for the corresponding offline problems, that provide optimality guarantees in terms of throughput, delay, and utility performance. The tutorial will also cover distributed, dynamic, algorithms, that are adaptable to changing user demands and network conditions. The tutorial targets both theorists and practitioners, interested in the modeling, analysis, and implementation of cache networks.
