Mobile ad hoc network is a type of self configurable, dynamic wireless network in which all the mobile devices are connected to one another without any centralised infrastructure.Since, the network topology of MANETs changes rapidly.It is vulnerable to routing attacks than any other infrastructure based wireless and wired networks.Hence, provid ing security to this infrastructure-less network is a majo r issue.This paper investigates on the security mechanis ms that are proposed for Selfish node attack, Shared root node attack and the Control packet attack in MANETs with the aid of a well known mu lticast routing protocol namely Mult icast Ad hoc On Demand Distance Vector (MAODV).The security solutions proposed for each of the above mentioned attacks are evaluated with the help of three evaluation parameters namely packet delivery ratio, control overhead and total overhead.The algorith mic solutions thus obtained are analysed in the simu lation environ ment by using ns-2 simulator.
