A Survey of Architectural Issues and Different Kinds of Attacks in Diversified Deployments of Wireless Sensor Networks

This paper focuses on the survey of various kinds of attacks in wireless sensor networks. The attacks of particular interest in almost all deployments of wireless sensor networks are Black hole and Wormhole attack. The area of particular interest is the attack detection in wireless sensor network. The wormhole attack is particularly challenging to deal with since the opponent does not need to compromise any nodes and can use laptops or other wireless devices to send the packets on a low latency channel. The contribution of this paper is two-fold. It discusses various techniques to detect and nullify the warmhole attacks in wireless sensor networks. It also discusses the key aspects of arechitectureal issues particularly in application layer that are of critical concern in wireless sensor networks.
