Analysis of Wormhole attack on MANETs using different MANET routing protocols

Mobile Ad Hoc Network (MANET) is a mutually communication based on a dispersed administration. It has a dynamic topology and there is not any central point for network management. The dynamic topology character of MANET has caused it vulnerable and defenseless to different security attacks. In this paper we study the effects of Wormhole attack on MANET using both Proactive routing protocol (OLSR) and Reactive routing protocol (AODV). The purpose of this study is to find which protocol is more vulnerable to the wormhole attack. The OPNET simulation results show the throughput, end-to-end delay, network load and traffic received with Wormhole and without Wormhole on AODV and OLSR in MANET. The results show that AODV is more vulnerable to wormhole attack compared to OLSR. Therefore, the application of MANET that uses proactive routing protocol is more trusted compared to the reactive one.
