WSN: Various Attacks and IDS in WSN

Intrusion detection in Wireless Sensor Network (WSN) is of practical interest in many applications such as detecting an intruder in a battlefield. The intrusion detection is defined as a mechanism for a WSN to detect the existence of inappropriate, incorrect, or anomalous moving attackers. Intrusion detection system in wireless sensor network is one of the growing research areas in recent years. Wireless sensor networks (WSN) consist of tiny devices. These tiny devices have limited energy, computational power, transmission range and memory. However, wireless sensor networks are deployed mostly in open and unguarded environment. Therefore, intrusion detection is one of the important aspects for wireless sensor networks. For the instrusion detection it is necessary to know the various attacks on WSN. In this report I mention several attacks on WSN and primarily focus only on the anomaly based intrusion detection system.
