Titel: Random Access in Communication Systems: Performance and Design

Abstract: Random multiple access protocols constitute a fundamental building block of communication networks as they allow users to share network resources in a fully decentralized way. These protocols have played, over the last four decades, a crucial role in the development of both wired and wireless access computer networks. Yet the performance of even the simplest of these protocols (such as slotted Aloha) is still not clearly understood. Their stability and optimal design have long eluded engineers and probabilists. In this talk, I review some recent advanced mathematical tools we developed to characterize their stability, and to devise new protocols with improved performance. These tools are based on methods from statistical physics and distributed stochastic optimization.
