Anomaly detection in wireless sensor networks

WSNs are usually composed of a large number of low power sensors. They require a careful consumption of the available energy in order to prolong the lifetime of the network. From the security point of view, the overhead added to standard protocols must be as light as possible according to the required security level. To provide security and privacy to small sensor nodes is challenging, due to the limited capabilities of sensor nodes in terms of computation, communication, memory/storage, and energy supply. Thus, WSNs need an Intrusion Detection System (IDS) to detect intrusion of adversaries to response and diminish the damage.
