In building next generation fixed wireless broadband networks, Wireless Mesh Networks (WMNs) have emerged as an important technology which provides low cost Internet access for fixed and mobile users. Peer-to-Peer (P2P) applications such as P2P file sharing have taken vertical rise with the evaluation of an orthogonal in computer networking. It is of interest to enable effective P2P file sharing in this type of networks. Herewith we contribute innovative schemes for content caching and replication at mesh routers that enhance the performance of P2P file sharing in WMNs. Initially we will display the impact of caching P2P content at mesh routers on the performance of P2P file sharing In WMNs. Later we demonstrate the design and operation of our content caching and replication sehemes, At the end we compare the performance of our proposed schemes against other existing schemes using simulations. The proposed schemes will support other applications also, though we focus on P2P file sharing.
