Energy Preserving Detection Model for Collaborative Black Hole Attacks in Wireless Sensor Networks

The security is a critical issue in wireless sensor networks (WSNs). A complex form of Denial of Service attack type is collaborative black hole attacks which challenge the security of wireless sensor networks. The purpose of this attack is to receive and drop all packets. Wireless sensor network nodes have limited energy and also have limited processing capability. WSNs devices have limited resources and they are particularly susceptible to the destruction and consumption of these limited resources. Collaborative black hole attacks are effective to partition the networks so the important data do not reach to base station. To secure wireless sensor network from collaborative black hole attacks, many security techniques have been proposed, most of them are energy inefficient and complex. In this paper, we discuss various techniques which detect and prevent the collaborative black hole attacks in WSNs and proposed a cluster-based energy preserving detection model of WSNs security against collaborative black hole attacks.
