DETECTION OF MALICIOUS NODE IN WIRELESS SENSOR NETWORK

The intrusion detection in Wireless Sensor Network (WSN) is of practical interest in many applications such as detecting an intruder in a field. The intrusion detection is defined as a system for a WSN to detect the existence of inappropriate, wrong or anomalous moving attackers. In this paper, I consider this issue according to heterogeneous WSN models. Furthermore, I consider two sensing detection models: single - sensing detection and multiple - sen sing detection... our results show the advantage of multiple sensor heterogeneous WSNs. In this system we assume an using single as well as multiple wireless sensor network .
