A novel distributed content replication and placement scheme for Wireless Mesh Networks

Abstract

In this paper, we aim to address the problem of content replication and placement in Wireless Mesh Networks (WMNs). Our main contribution is to propose an innovative, distributed and scalable content replication and placement heuristic that places content at mesh routers to improve the network performance in terms of bandwidth consumption and latency perceived by mesh clients. We first introduce our proposed heuristic by presenting the effect of object replication at mesh routers on the performance of the WMNs. We then describe our proposed replica placement heuristic. Finally, we present our preliminary results on the performance of the proposed heuristic. The results show that the proposed heuristic can achieve a significant performance gain in terms of object access cost, throughput and latency.
