A New Collaborative Approach for Intrusion Detection System on Wireless Sensor Networks

Abstract

Due to its characteristics, the Wireless Sensor Networks (WSN) are useful in a variety of applications such as environmental monitoring, surveillance, tracking, among others. Given the nature of such applications, where many are mission critical, the WSN become targets of possible attackers interested in harming the network. Among the defense mechanisms, the intrusion detection systems play important role in detecting attacks that can overcome the preventing techniques. This paper proposes a new collaborative and decentralized approach for intrusion detection system. Special nodes, called monitors, will be responsible for monitoring the behavior of neighbor nodes. The malicious activities evidences discovered by each monitor will be shared and correlated with the purpose of increasing the accuracy in detection of intruders. Experiment conducted by simulation show that our solution is effective in reducing the false positives.
