Mitigating the gateway bottleneck via transparent cooperative caching in wireless mesh networks
Saumitra M. Das, Himabindu Pucha, Y. Charlie Hu · ACM SIGMOBILE Mobile Computing and Communications Review · 2007
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.
