Lightweight Intrusion Detection for Wireless Sensor Networks

Abstract

In recent years, wireless sensor networks have many potential applications for both civil and military tasks. However, sensor networks are susceptible to many types of attacks because they are deployed in open and unprotected environment. So it is necessary to use effective mechanisms to protect sensor networks against many types of attacks on routing protocols. Intrusion detection is one of the major and efficient defense methods against attacks in a computer network and system. Because of different characteristics of sensor networks, security solutions have to be designed with limited usage of computation and resources. In this paper, we proposed a hybrid, lightweight intrusion detection system integrated for sensor networks. Our intrusion detection scheme take advantage of cluster-based protocol to build a hierarchical network and provide an intrusion framework based both on anomaly and misuse techniques. Our scheme can prevent most of routing attacks on sensor networks.
