This paper discuss various techniques of intrusion detection in wireless sensor networks available. This paper gives an introduction to wireless sensor networks, security in WSN and describe various techniques used to overcome attacks. The prevention techniques according to the network structure of WSN and a convenient method of intrusion detection and prevention in wireless sensor networks are studied in this paper. Thus, the papers main aim is to include the most recent advancements in this area as well as to predict the future course of research so that the general as well as expert readers could be greatly benefited.
