Abstract: Peer-to-peer networks are gaining popularity due their decentralized nature. Among different approaches to the network, structured overlay network using tree topology is the most preferred one. However, one of the main problems of a peer-to-peer tree is guaranteeing fault tolerance in the presence of node failure. Since fault tolerance is crucial for a peer node, there is a need for a fault detection and recovery technique. In this proposal, we propose a fault detection and recovery mechanism in the tree-based peer-to-peer network. We introduce an ALIVE packet concept which is used for detecting faulty nodes and recovering from the faults when the server is overwhelmed by more number of requests from many clients. Server replication (Virtual Peer) method is adapted in the system to achieve high efficiency for range queries while providing consistency among virtual peers.
