Mitigating routing misbehaviour in self organizing mobile ad hoc network using K-neighbourhood local reputation system
The performance and nodes behaviour in the wireless sensor networks are affected by malicious nodes. These malicious nodes alter and degrade the network performance. In this paper, a hybrid Acknowledge scheme is proposed for the detection of malicious nodes in the wireless sensor networks. The nodes in the wireless sensor network are grouped into number of clusters. Each cluster possesses only three nodes and has an individual cluster key in all nodes in the cluster. The individual cluster key is provided to each cluster in the network by the sink. The malicious nodes are detected by receiving the acknowledgement from the destination node. The performance of the proposed system is analyzed and evaluated in terms of latency and packet delivery ratio. The proposed system is tested by determining the performance parameters at three types of attacks on the nodes in the network.
