A Survey on Various Mechanisms to Detect and Remove Collaborative Attacks in MANETs

Abstract

Mobile Adhoc Network (MANET) are used most commonly all around the world.This is because the mobile nodes has the ability to communicate with each other without any fixed network.The nodes in mobile adhoc network has the tendency to make decisions on its own that is autonomous state.A security solution is very much needed for networks to protect both route and data forwarding operations in the network layer .Security is an essential requirement in MANET.Without any proper security solution ,the attacker node in the network will act as a normal node which causes eavesdropping and selective forwarding attack generally known as Gray hole attack.In this paper a survey about various security mechanisms for Gray Hole attack is proposed to detect and remove collaborative Gray Hole attack that occurs in network layer in MANETs.
