ABSTRACT

Advances in electronics and wireless communication technologies have enabled the development of large-scale wireless sensor networks (WSNs). However, WSNs practice from lots of constraints, with low computation capability, small memory, limited energy resources, vulnerability to physical capture, and the need of infrastructure, which enforce lonely security challenges mostly for the applications where confidentiality has key significance. There are diverse applications for wireless sensor networks, and security is very major issue for several of them. Before attackers can damage the WSN system (i.e., sensor nodes) and/or information destination (i.e., data sink or base station) in order to work WSNs in a secure way, any sort of intrusions should be detected.
