Design of a New Intrusion Detection System of WSNs

The open access and limited resources of WSNs make the network vulnerable to all kinds of attacks, and for this reason it requires effective intrusion detection technology to detect and identify various security threat. This paper firstly gives a brief introduction of the present intrusion detection system, and then discusses the various threats faced of WSNs, at last this paper points out that the comprehensive use of various technologies is the trend of the intrusion detection system of WSNs.
