Co-operative Approach to Detect Misbehaving Nodes in MANET Using Multi-hop Acknowledgement Scheme

Mobile ad hoc networks are a wireless network in which each node is vested with the responsibility to act as a router. The individual nodes are constrained by the resources such as battery power. To achieve maximum throughput with the available resources the nodes might behave selfishly. This could lead to severe performance degradation in network throughput, packet delivery ratio, packet loss increment, etc. To mitigate this problem of routing layer misbehavior we analyze the existing misbehavior detection schemes and propose a novel solution. In the proposed scheme we use multi hop acknowledgement to detect misbehaving nodes.
