Fast and Accurate Event Detection Based on Wireless Sensor Networks Using Fuzzy Logic Method

Abstract:

Wireless Sensor Networks have recently been used for environmental monitoring and real time event detection because of their low implementation costs and distributed sensing and processing capabilities. Event detection is a critical issue in wireless sensor networks. Fire detection is used as an example in our event detection system. Algorithms are required to detect fire sensors and measure the environmental parameters (temperature, humidity, light intensity, and Carbon Monoxide) to determine if a fire is present or not. It is urgent to research fire detection techniques that are efficient, convenient and practical. Although there are several works on fire detection using WSNs, sufficient attention has rarely been paid to using fuzzy logic methods. We present a novel approach based on fuzzy logic for multi-sensors data fusion in a wireless sensor network system with a node-sink mobile network structure to detect fire. Through simulation results, it is shown that the proposed innovative fuzzy logic algorithm can improve the reliability and accuracy of sensed information and reduce the rate of false alarm.
