Abstract:
Abstract - Mobile Ad-hoc Networks (MANETs) are always deployed in the situation, where there is no fixed infrastructure but networks are susceptible to compromise due to its fundamental characteristics as open media dynamic topology and lack of centralized monitoring. In such a scenario, designing an efficient and secure routing protocol has been a major challenge. This paper study impact of resource depletion RREQ flood attacks of our proposed Neighbour Defence Technique for AODV (NDTAODV) with that of Secure Ad Hoc On-demand Distance Vector (SAODV) and Ad Hoc On-demand Distance Vector (AODV) routing protocol by varying malicious nodes in MANETs with respect to four major performance metrics such as Packet Delivery Fraction (PDF), Average Throughput (AT), End-to-End Delay (AED) and Normalized Routing Load (NRL). Simulations results demonstrate that the NDTAODV gives better security and performance than the AODV and on a par with that of SAODV with improved AED and NRL without using any lengthy complex cryptography processing on the mobile node in MANETs unlike SAODV. Keywords- MANETs, AODV, NDTAODV, SAODV, Cryptography, Routing Protocol, Route Request (RREO), Route Reply(RREP), PDF, AT, NRL.
