Abstract:
Identifying misbehaviors is an important challenge for monitoring, fault diagnosis and intrusion detection in wireless sensor networks. A key problem is how to minimise the communication overhead and energy consumption in the network when identifying misbehaviors. Our approach to this problem is based on a distributed, hyperspherical cluster-based anomaly detection algorithm. We minimise the communication overhead by clustering the sensor measurements and merging clusters before sending a description of the clusters to the other nodes. This talk will describe our algorithm and share the experience in implementing the distributed algorithm on Sun SPOT wireless sensor nodes.
