Comparison of Attacks on Wireless Sensor Networks

Wireless sensor networks consist of individual nodes that are able to interact with the environment by sensing or controlling physical parameters. These nodes have to collaborate to fulfill their tasks. The nodes are interlinked together and by using wireless links each node is able to communicate and collaborate with each other. In this paper, we focus on security issues of WSNs; small survey on the main challenges of these networks, a wide variety of WSNs’ attacks and a comparison between them. Also, this paper discusses known approaches of security detection and defensive mechanisms against the link layer attacks; this would enable IT security managers to manage attacks of WSNs more effectively.
