Wireless Sensor Network based: Design Principles & measuring performance of IDS

Wireless sensor networks have many potential applications for both civil and military tasks. However, sensor networks are susceptible to many types of attacks because, deployed in open and unprotected environment. For these cases, it is necessary to use some mechanism of intrusion detection. Besides preventing the intruder from causing damages to the network, the intrusion detection system (IDS) can acquire information related to the attack techniques, helping in the development of prevention systems. So it is necessary to use effective mechanisms to protect sensor networks against many types of attacks. Intrusion detection system is one of the major and efficient defensive method against attacks on wireless sensor network. Because of different characteristics of sensor networks, security solutions have to be designed with limited usage of computation and resources. In this paper different Intrusion detection systems are analyzed basis on design and performance in real time wireless sensor network environment.
