Malicious Node Detection in Adhoc Wireless Sensor Networks Using Secure Trust Protocol

Abstract

Recent researches in different perspectives and industrialized oriented applications have broadly utilized wireless Sensor Network (WSN). At present, WSN have attained specialist attention for providing secure networks, which is free from attackers and malicious nodes. WSN security is subject to threats by assaulters. It needs sensor to periodically sense and transmit sensitive data to BS for data transmitting commonly through multi hop path. As, it is very essential to design the secure AdHoc network to detect the smart attackers efficiently. Here in this paper we design trust based secure network for detection of attacks due to presence of malicious nodesutilizing secure trust protocol (STP) scheme of AdHoc wireless sensor network. Clustered Heterogeneous Routing Protocol (CHRP) has been used to improve network security. Using factors including throughput, minimal end-to-end delay, packet transmission rate, energy conservation rate, and attack detection rate, experimental results demonstrate better network security.
