A System for Distributed Event Detection in Wireless Sensor Networks

Free registration required

Executive Summary

Event detection is a major issue for applications of wireless sensor networks. In order to detect an event, a sensor network has to identify which application-specific incident has occurred based on the raw data gathered by individual sensor nodes. In this paper, an event may be anything from a malfunction of monitored machinery to an intrusion into a restricted area. The goal is to provide high-accuracy event detection at minimal energy cost in order to maximize network lifetime. In this paper, the authors present a system for collaborative event detection directly on the sensor nodes.
