INVESTIGATION ON WSN ROUTING PROTOCOL IN IEEE802.15.4 BASED WSN UNDER WORMHOLE ATTACK

Abstract

Wireless sensor networks (WSNs) is one of the most challenging technologies with many application ranging from health care to military applications. In many important military and commercial applications, it is critical to protect a sensor network from malicious attacks. One of these attacks which is hard to detect and mitigate is wormhole attack which presents a demand for strengthen the security mechanisms in the network. In this paper, the performance of zigbee based wireless sensor networks using routing protocols with wormhole attacks has been investigated. This Paper illustrates how wormhole attacks can affects the performance of Ad hoc On-Demand Distance Vector (AODV) routing protocol, Optimized Link State Routing (OLSR) and Zone Routing Protocol (ZRP) in zigbee based WSN by using Qualnet Simulator 5.0. The metrics used to analyse the performance of routing protocol of WSNs are throughput, Average end-to-end delay and total energy consumption of sensor network.
