Intrusion detection system in wireless sensor networks: A comprehensive review

In today's era security is one of the main concern in every field also in wireless sensor networks. Resource limitation is main concern of sensor nodes in wireless sensor networks. There are many security threats which are affecting the, functionality, security and network life time of and wireless sensor networks. In this paper security threats, security goals, various attacks, classification of these attacks are presented along with the comparison of different intrusion detection systems in wireless sensor networks. Detailed information about intrusion detection systems is provided then, intrusion detection methodologies are compared based on different schemes. Intrusion detection schemes are categorized based on techniques used in the scheme: Specification based scheme, computational intelligence and data mining based scheme, game theory approach based intrusion detection scheme, probability distribution based detection scheme. At the end of paper advantages and disadvantages of each scheme is also presented.
