Empirical Study of NDTAODV, SAODV and AODV Routing Protocol in the presence of RREQ Flood Attacks in MANETs

摘要

Mobile Ad-hoc Network (MANET) is a decentralized wireless network, in which, mobile nodes are free in moving in and out from the network. MANET has several independent nodes that organize themselves in different ways and work without strict top-down network administration. In this scenario, designing a secure and efficient routing protocol with less delay and overheads is a major challenge. In this paper, extended work of our proposed Neighbour Defense Technique for AODV (NDTAODV) is presented and studied the impact of resource depletion RREQ flood attacks of NDTAODV with Secure Ad-hoc On-demand Distance Vector (SAODV) and Ad-hoc On-demand Distance Vector (AODV) protocol wherein a number of source node communicating in MANETs are varying. For the assessment of performances, Packet Delivery Fraction (PDF), Average Throughput (AT), End-to-End Delay (AED), and Normalized Routing Load (NRL) are considered. Simulation results demonstrate that the NDTAODV gives better security and outperform the AODV in all performance metrics and nearly same result as that of SAODV with improved AED and NRL without using any complex cryptography processing on the mobile node in MANETs.
