IMPROVING THE SECURITY BASED ROUTING PROTOCOL FOR WIRELESS SENSOR NETWORKS

Wireless sensor networks (WSNs) have become one of the most popular wireless communication systems in the world. Various attacks have been launched against the WSN individual nodes over the past few years, and the overall security of the network has gradually deteriorated. In this research, we propose a secure uneven clustering method for WSN. The proposed method is based on a trust score evaluation model with the objective of identifying malevolent users in WSNs. The trust score is used to determine whether or not a node is malicious. The results show that the proposed Trust Algorithm outperforms the currently used LEACH algorithm, the TASRP algorithm and the FLSO algorithm in terms of the percentage of packets that are successfully delivered across all use cases and density of nodes.
