MobiCom Poster Abstract: Mitigating the Gateway Bottleneck via Transparent Cooperative Caching in Wireless Mesh Networks

Wireless mesh networks (WMNs) are characterized by mesh routers connected by wireless links to each other and to a few gateway nodes. The most significant application of such networks is to provide broadband Internet access to static or mobile hosts in areas where wired infrastructure is difficult or economically infeasible to deploy. Since most WMN traffic flows through a few gateway nodes, this can cause significant congestion around the gateway. Previous studies have shown that significant locality exists in Internet accesses from a given population of clients. Web caching has been proposed and extensively studied to exploit such locality in reducing the Internet traffic and the client-perceived access latency. We anticipate that similar locality will exist i
