Although static sensor nodes have low computation and communication capabilities,but they have specific properties,and can acquire stable neighborhood information,which can be used for detection of anomalies in networking and behaviors of the neighbor nodes,to provide security for wireless sensor network.To make a sensor node capable of detecting an intruder,a simple dynamic statistical model of the neighboring nodes is needed to build,with a low-complexity detection algorithm to monitor received packet power levels.A detection algorithm based on security scheme for wireless sensor networks was introduced,and then a novel node cooperative detection technology based on this detection algorithm,which refers to affirm and stand against intrusion together,was proposed.
