Evaluation of Intrusion Detection Schemes in Wireless Sensor Network (original) (raw)

Wireless Sensor Network (WSN) consists of sensor nodes, which communicate wirelessly in order to perform some specific operation. Wireless Sensor Network (WSN) is implemented in open medium environment and the sensors nodes are fully distributed in nature. In order to communicate with each other a multi hop communication should be used. Moreover, WSNs have limitations in terms of computations, memory, bandwidth, and energy. The distributed nature, multi hop data forwarding, and open wireless medium are the factors that make WSNs highly vulnerable to security attacks at various levels. Intrusion Detection Systems (IDSs) can play an important role in detecting and preventing security attacks. IDS is capable to detect an intrusion and raise an alarm for appropriate responses. The aim of this paper is to provide a detailed review about current IDS schemes for WSN. Finally we focus on comparison of recent Intrusion Detection Schemes in WSNs.
