Selfish node detection in Wireless Mesh Networks

Wireless Mesh Networks (WMNs) are multi-hop network in which each node communicates with each other to increase the performance of network. Security is a big challenge in WMNs. The network always faces different types of security attacks by external and internal intruders. Most of the time these intruders are the internal legitimate nodes of the network that behave abnormally and network becomes unsecure. In this paper a novel secure routing approach is proposed that identify the internal intruders in the network using field base routing algorithm. This proposed technique has been extensively studied using OMNet++ network simulator to secure the network from the internal attacks by the legitimate nodes.
