A PSO Based Malicious Node Detection and Energy Efficient Clustering in Wireless Sensor Network
Sumit Kumar, Shabana Mehfuz · 2019
In the Wireless sensor network (WSN) clustering is one of the most important tasks in which any one of the nodes from a collection of nodes is chosen to be a cluster head and cluster head takes care of mainstream functioning as well as dealing with the other nodes within the cluster. Also in the wireless sensor network (WSN), malicious node detection is the crucial task, so that the malicious node can never become the cluster head. Further, as the number malicious node increases, then the possibility of becoming a malicious node as cluster head also increases. So as to detect malicious node as well as to select a high potential node for cluster head, a PSO based malicious node detection and cluster head selection technique is proposed. The proposed algorithm determines a potential worth for all nodes thereafter a high potential node is chosen as a cluster head. This algorithm also reduces cluster overlapping with spatial allotment of cluster heads as well as removing malicious nodes specifically not permits malicious nodes to become cluster heads with overall improvement in energy efficiency.
