Survey on Reputation and Trust in MANETS

Wireless Self organizing networks rely[1] on node cooperation to perform and support basic functions like packet forwarding, routing and network management . Lack of Infrastructure, resource constraints and organizational environment of self organizing nodes make them vulnerable to newer threats and challenges. By default, [2] non- cooperative misbehavior activities of the nodes will slowly lead to the performance deterioration of the network. Hence the responsibility of ensuring security and Integrity is its vital role of these self organizing networks. Cooperation enforcement schemes [3] like reputation and trust provides a supplementary security to protect basic network operations from misbehavior threats of the internal nodes.
