Cluster Head and RREQ Based Malicious Behaviour Detecting and Preventing Approach in WSN

Abstract

Wireless sensor network is a type of network which has no communications pattern for communicate between nodes, new nodes easily integrate in network so attacks easily deploy on it. Gray hole is additionally one of the attacks that are tough to notice as a result of it will behave each as normal node and malicious node. For detecting and preventing malicious behavior of node we propose a technique Cluster head and RREQ based malicious behavior detecting and preventing approach in WSN. In our propose work we select a node which have highest energy as a cluster head and remaining node work as a cluster member, for each node we decide a thresh hold for sending RREQ if any node generate RREQ more than thresh hold than we check its RREP thresh hold value if it’s less than one than cluster head broad cast the node id of this node so that all node drop the request arrive from this malicious node, and for gray hole detection if node does not send RREP frequently then for checking its malicious behavior we send RREQ which is generate by flooder node if any node reply positively so same as we do with this malicious node and drop the route which is generate by this malicious node.
