Mesh-dht Approach for Efficient Resource Sharing in P2p Based Wireless Mesh Network

Wireless Mesh Networks (WMN) is a popular communication paradigm due to its low cost and rapid deployment. A large-scale WMN needs a look-up structure to support storage, client mobility and generic services. A Distributed Hash Table (DHTs) spreads construction and maintenance load of abstract index infrastructure over participating nodes, providing simple data access interface. The existing Location aware chord protocol incorporates nodes locality in DHT construction. In addition to node locality, we have proposed MESH-DHT that considers the Link Quality, End to End Delay, Query Response time, Packet Delivery Ratio to improve the QoS parameters in a P2P based Wireless Mesh Network. As WMN’s Quality of Service (QoS) parameters are Non-Deterministic Polynomial (NP) hard problem, we have proposed Particle Swarm Optimization (PSO) to improve the QoS parameters of chord when deployed over a multihop environment like Wireless Mesh Networks.
