Ad-hoc sensor network are exciting research area in pervasive computing. There are lots of protocols established to protect from DOS attack, but it is not perfectly possible. One such DOS attack is vampire attack. This vampire attack is a resource depletion attacks at the routing protocol layer, which permanently disconnect the networks by quickly draining nodes' battery power. These \"Vampire\" attacks are not specific to any specific protocol, but rather depend on the characteristics of many popular classes of routing protocols.
