Talk Title: Towards Stochastic Geometry for Smart Cities and Internet of Things
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Stochastic geometry deals with the study of random spatial patterns. Such patterns appear in all major technological systems of critical importance to smart cities, such as communication networks, transportation, and smart grid. For instance, locations of wireless nodes, vehicles, and electric vehicle charging stations can all be visualized as random point patterns and can hence be modeled as point processes. Somewhat less obviously, the layout of roads in a city can also be visualized as a random spatial pattern (and can hence be modeled as a line process).
In this talk, our focus will be on doubly-stochastic spatial models and their applications to problems of interest to communications and CPS communities. We will start our discussion with networks formed on roadways. In order to model these networks, we will construct a doubly-stochastic model in which the layout of roads is modeled using a line process and locations of vehicles (and other infrastructure elements) on each road as a Poisson point process. Using this model, we will first characterize the performance of a wireless link formed by a typical vehicle with another vehicle in the same network. This basic construct can be used to characterize wireless performance in emerging V2X/C-V2X technologies. We will then apply the same model to study the problem of infrastructure placement (such as electric vehicle charging stations) along the roads. In such problems, we generally need to measure distances along the roads (similar to Manhattan distance) because of which the resulting analysis has a significantly different flavor compared to that of wireless networks. In the remaining time, we will focus on Poisson cluster process, which is a doubly-stochastic spatial model that is useful in capturing spatial coupling in the locations of wireless nodes. We will discuss its applications to both Internet of Things and cellular networks (time permitting). Interested readers can refer to the following two representative papers to get more rigorous details: https://arxiv.org/abs/1709.08577 (line process) and https://doi.org/10.1109/TCOMM.2017.2782741 (cluster process).
