Packet Forwarding Method by Clustering Approach to Prevent Vampire Attacks in Wireless Sensor Networks

Vijimol Vincent K, D.Prabakar

Wireless ad hoc sensor networks and transmission of data in them is a significant research area. Security is established in sensor networks using different types of protocols. But it is not completely possible. One such DOS attack is Vampire attack, which makes permanent unavailability of the networks by draining the power of each node in the networks. This paper presents a method to bound the damage caused by vampire attack by using the Cluster Head. If any Vampire attack is present in the network, the Cluster Head engages in the situation and delivers the packet to sink without dropping the packet. Thus it provides a successful and reliable message delivery even in the presence of Vampire attack.
