A Literature Survey on Detection and Prevention Against Vampire Attack in WSN

摘要

Wireless sensor network (WSN) is an ad hoc low power wireless network in which sensor nodes cooperatively monitor and gather the information from environment then broadcast that information to other nodes. So security against denial of services (DoS) at routing levels is the most significant area of research. In this paper, denial of service at the routing level are discussed. DoS is cause by resource exhaustion at the network layer, which completely disable the network by consuming node's battery power. This power draining attack is known as "vampire attack" which is not definitive to any routing protocol. A single Vampire can raise network energy usage by a factor of O(N) in worst case, here N is the number of nodes. This paper reviews some methods to detect and mitigate this attack that raise the energy consumption of network and concepts that bounds the damage from Vampires.
