Abstract
Trust in wireless sensor network is an essential feature to detect various kind of attacks in the network. Wireless sensor nodes are more prone to attacks as nodes are deployed in an open environment. In case of centralized low energy adaptive cluster head protocol cluster heads in each round are selected by sink node. We propose a trust factor based LEACH-C protocol, to detect malicious nodes based on trust calculations which involves observation of various parameters and evaluation of trust factors. Simulation is conducted in using NS-2, by varying the number of malicious nodes and results are analyzed for energy consumption, number of data packets sent and percentage of malicious node detection.
