EXHAUSTING VERVE BY VAMPIRE’S IN WIRELESS AD HOC SENSOR NETWORKS?

Vampire attacks are not specific to any specific protocol, but rather rely on the properties of many popular classes of routing protocols. A single Vampire can increase network-wide energy usage by a factor of O(N), where N in the number of network nodes. This paper will use two attack on stateless protocol in which first Carousel attack is an adversary sends a packet with a route composed as a series of loops, such that the same node appears in the route many times. Second, Stretch attack where a malicious node constructs artificially long source routes, causing packets to traverse a larger than optimal number of nodes. The vampire attack are very difficult to detect and more over very difficult to prevent.
