Security is a significant concern for many sensor network applications. Intrusion detection is one method of defending against attacks. However, standard intrusion detection is not suitable for sensor networks with limited battery power, memory and processing resources. This paper compares several approaches to intrusion detection in sensor networks. We investigate accuracy of detection of attacks versus energy efficiency. Existing solutions are compared with a new adaptive protocol for distributed defense
