Security Issues and Its Counter Measures in Mobile Ad Hoc Networks

Abstract

The dynamic topology of MANETS has made them vulnerable to security threats. This research work focuses on the Security Issues in Mobile Ad-Hoc Network, the different types of attacks in MANETS, the existing security mechanisms and the solutions approaches in the security of different applications of MANETS. The prime objective of the work is to provide a generic solution approach which can be implemented before initiating the working on any MANET security algorithm, so as to provide better results and security. NS-2 simulator is used to make the network topology on MANETS and analyse them using the trace files obtained when using different routing protocols like AODV, DSDV. An algorithm is proposed to detect the popular nodes, the critical nodes, the potentially malicious nodes in a network, for every rounds of time. The cluster based approach is used by which all the details of parameters evaluated in terms of critical nodes, potentially malicious nodes and popular and non popular nodes can be send to the cluster heads for performing further action using the other existing security algorithms.
