Wireless Mesh Networks (WMNs) have emerged as an important technology in building next generation fixed wireless broadband networks that provide low cost Internet access for fixed and mobile users. An orthogonal evolution in computer networking has been the rise of Peer-to-Peer (P2P) applications such as P2P file sharing. It is of interest to enable effective P2P file sharing in this type of networks. The authors' main contribution in this paper is innovative schemes for content caching and replication at mesh routers that enhance the performance of P2P file sharing in WMNs. They first motivate their proposed schemes by showing the impact of caching P2P content at mesh routers on the performance of P2P file sharing in WMNs.
