OVERCOME VAMPIRE ATTACKS PROBLEM IN WIRELESS AD-HOC SENSOR NETWORK BY USING DISTANCE VECTOR PROTOCOLS

Adhoc sensor wireless networks has been drawing interest among the researches in the direction sensing and pervasive computing. The security work in this area is priority and primarily focusing on denial of communication at the routing or medium access control levels. In this paper the attacks which is mainly focusing on routing protocol layer that kind of attacker is known as resource depletion attacks. This attacks causing the impact of persistently disabling the networks by drastically draining the node’s battery power. These “Vampire” attacks are not impacting any specific kind of protocols. Finding of vampire attacks in the network is not a easy one. It’s very difficult to detect, devastating .A simple vampire presenting in the network can increasing network wide energy usage. We discuss some methods and alternative routing protocols solution will be avoiding some sort of problems which causing by vampire attacks.
