Abstract:
Mobile Ad Hoc Networks (MANET) are continuously self-organizing wireless networks with no fixed infrastructure, where network communication is established without a centralized administration. Security is an important issue for mobile ad hoc networks, due to the vulnerable nature of MANETs. This paper describes the effects of Pulse Jammer attack, Misbehavior Node attack and Byzantine attacks on the network performance under different traffic loads using Geographic Routing Protocol (GRP), Proactive Routing Protocol such as Optimized Link State Routing (OLSR) Protocol and Reactive Routing Protocols such as Ad Hoc On Demand Distance Vector (AODV) Routing Protocol and Dynamic Source Routing (DSR) Protocol. The impact of security attacks on MANET performance is evaluated by investigating which attack is more harmful to the network. IEEE 802.11b and 802.11g standards are compared with respect to the Pulse Jammer attack, Misbehavior Node attack and Byzantine attack for AODV Routing Protocol. Simulation results using OPNET simulator show that the efficient utilization of the network reduces considerably in the presence of the mentioned attacks.
