Abstract: Intrusion detection in Wireless Sensor Network (WSN) is widely used in many applications such as detecting an intruder. The intrusion detection is a mechanism for a Wireless Sensor Network to detect the existence of inappropriate, incorrect or unsuspicious moving attackers. WSN consumes lots of energy to detect an intruder. The main objective of this approach was developed under JFrame Builder tools is to provide simple and secure algorithm for energy efficient approach for external intrusion as well as internal intrusion detection. Wireless sensor networks (WSNs) often consist of tiny devices with limited energy, computational power, transmission range, and memory. WSNs offer a variety of potential means to monitor environments. Furthermore, we consider two sensing detection models: single-sensing detection and multiple-sensing detection. Our simulation results show the advantage of multiple sensor heterogeneous WSNs.
