Route Redirection in Structured Network Using Chord

In a structured peer-to-peer (p2p) network, Distributed Hash Tables (DHT) are maintained by nodes to store information and to route the packets. But sometimes a node can be attacked and so it may deny the DHT key access or misroute the packets. Replica Placement is a key mechanism to overcome these problems by placing replica for nodes in p2p network. MAXDISJOINT replica placement strategy creates disjoint routes that redirects the routes from source to destination nodes. Another replica placement strategy is Spaced replica placement where replica identifiers are separated by uniform spacing. Our proposed work is to make efficient placement of replicas by combining MaxDisjoint and Spaced replica placement and thereby reducing its implementation cost.
