Prevention of flooding attacks in mobile ad hoc networks

Abstract

Mobile ad hoc network (MANET) in spite of having numerous advantages is still vulnerable to various security breaches. Most of the attacks in MANET are initiated during route discovery process. Flooding attack is found to be most destructive because its severity often leads to exhaustion of resources and bandwidth of MANET. In this paper in order to confront the flooding attack, a new two-step protection method (TSPM) is proposed. The analysis of obtained simulation results with the proposed TSPM establishes that the proposed method detects and isolates the attackers efficiently.
