TRUST BASED CLUSTER HEAD SELECTION WITH SECURE ROUTING ALGORITHM FOR WIRELESS SENSOR NETWORK

Abstract

            Wireless sensor networks (WSNs) contain an excellent quantity of battery-driven small nodes that have sensing, computing and communication capabilities. Therefore, it's essential to design an energy-efficient routing protocol to cleverly use the limited energy of WSNs. One-way of managing the energy efficiency is grouping sensors to form a cluster and choose a node as lead to manage referred to as cluster head (CH). In case a malicious node or lower energy node is chosen as a cluster head, the throughput of the network is greatly affected. Thus selection of cluster heads with higher trust and residual energy becomes crucial for the overall network performance. To deal with this problem, this work proposes a Trust based Cluster Head Selection with Secure Routing (TCHS_SR) algorithm for wireless sensor network. The proposed method relies on an effective distributed trust model for cluster head selection and it also considers the secure route for data transfer. The experimental result shows that the proposed TCHS_SR algorithm reduces energy consumption and end-to-end delay, furthermore increases the throughput and packet delivery ratio efficiently.
