Title: On the entropy of wireless networks
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
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.
