P2P file sharing in wireless mesh networks

In wireless mesh networks, the connective time would be relatively short in multi-hop nodes because of the mobility of peer nodes and the wireless collision. Therefore, it is important that how peers choose reasonable schemes to gain more benefits and improve the networks performance when they implement the peer-to-peer file sharing in limited environment. On the basis of the researches of peer-to-peer file sharing and the inherent characteristic of wireless mesh networks, a novel venture investment based file sharing model is proposed. The model provides a mechanism to maximize investment benefit and minimize investment venture, and makes optimization investment schemes through a benefit evaluation method. The simulation results show that the venture investment model can assist networks nodes to invest file sharing effectively and improve the performance of networks.
