Title: On the entropy of wireless networks

Speaker: Associate Professor Justin P. Coon

Abstract: As the era of 5G and the IoT looms, the densities and complexities of wireless networks are increasing at an astonishing rate.  It is particularly interesting, and rather unsettling, that this evolution is taking place without a full understanding of whether or not this scaling is sustainable, or even possible.  The reason for this omission is primarily due to the fact that, until now, the engineering community has not had a quantitative framework for analyzing wireless network properties such as scalability, complexity, topological uncertainty, and stability.  In this talk, we will introduce such a framework by developing the formalism of spatial graph entropy in the context of wireless communication networks.  After providing a pedagogical introduction to this topic, we will present a number of analytical results reported over the last two years, and propose potential uses for the new formalism to enhance wireless network performance.

Title: Node Deployment in Heterogeneous Wireless Networks

Speaker: Professor Hamid Jafarkhani

Abstract: Wireless networks of the future, such as the Internet of Things, are  envisioned to be highly heterogeneous. In many applications, one is interested in optimally deploying a network of nonidentical nodes to a certain area of interest. These networks may include a multitude of connected autonomous nodes in one or more tiers. We formulate these deployment problems as quantizer design problems where different distortion measures should be associated with different quantization indices. We discuss fundamental design challenges like the best spatial  deployment of nodes to minimize the energy consumption or maximize the sensing accuracy while guaranteeing network connectivity. This is done by developing a quantization theory of heterogeneous reproduction points. We will discuss the characteristics of such a heterogeneous quantization  theory and show that some of the standard results of the traditional quantization theory, including Gersho's conjecture, do not hold.

Title: Network Slicing for Service-Oriented Networks Under Resource Constraints

Speaker: Professor Zhi-Quqan Tom Luo

Abstract: To support multiple on-demand services over fixed communication networks, network operators must allow flexible customization and fast provision of their network resources. One effective approach to this end is network virtualization, whereby each service is mapped to a virtual subnetwork providing dedicated on-demand support to network users. In practice, each service consists of a prespecified sequence of functions, called a service function chain (SFC), while each service function in a SFC can only be provided by some given network nodes. Thus, to support a given service, we must select network function nodes according to the SFC and determine the routing strategy through the function nodes in a specified order. A crucial network slicing problem that needs to be addressed is how to optimally localize the service functions in a physical network as specified by the SFCs, subject to link and node capacity constraints. In this paper, we formulate the network slicing problem as a mixed binary linear program and establish its strong NP-hardness. Furthermore, we propose efficient penalty successive upper bound minimization (PSUM) and PSUM-R(ounding) algorithms, and two heuristic algorithms to solve the problem. Simulation results are shown to demonstrate the effectiveness of the proposed algorithms.
