Content Dynamics Over the Network Cloud

Abstract

The project was concerned with dynamics in telecommunication networks, with principal focus on peer-to-peer dissemination systems. A first line of work was to develop the theory for a fluid-PDE model for content evolution in peer-to-peer networks. We rigorously proved its mathematical relationship with queueing systems. We also included heterogeneity in the model for peer access bandwidth. The PDE dynamics was analyzed comprehensively froma control-theoretic perspective. A second line of contributions referred to the relationship between the microscopic mechanisms for piece exchange in peer-to-peer, and the resulting bandwidth allocation. We studied a proportional reciprocity mechanism which allows for a mathematical prediction of performance, and studied how to approximate this allocation through neighbor selection, using the Gibbs sampler. A third line concerns dissemination in wireless ad-hoc networks, in which P2P communication bandwidths are influenced by location. Optimal sharing schemes tailored to this setting were analyzed.
