Abstract:
ABSTRACT Several studies in the literature have been addressed by the researchers to solve security dilemmas of Mobile Ad-Hoc Networks (MANET). Due to the wireless nature of the channel and specific characteristics of MANETs, the radio interference attacks cannot be mitigated through conventional security mechanisms. These attacks cause a significant degradation on overall network throughput, packet transmission rates and delay on the MAC layer since other nodes step back from the communication. A malicious node can continually transmit a radio signal in order to block any type of legitimate access to the medium and/or infer with reception. This phenomenon is called as jamming and the malicious nodes are termed to as jammers. MANET routing protocols could improve system performance by increasing throughput and data dropped. To minimize the impact of the disruption, it is important to identify its presence. So, in this paper, a meliorated detection mechanism has been proposed in order to detect the physical jamming attacks in Ad Hoc On Demand (AODV) Routing protocol and Dynamic source routing (DSR) protocol thereby increasing the throughput and decrease the delay. The results of the proposed technique are compared under both these protocols with respect to throughput and delay. Keywords: AODV, defense, delay, DSR, jamming attack
