A Decentralized Approach for Detecting Dynamically Changing Diffuse Event Sources in Noisy WSN Environments

Abstract

Localizing dynamically changing diffuse event sources in real environments is still an open problem in Wireless Sensor Networks (WSN). The dynamism of the environment, the energy limitations of the sensors, and the noise associated to the sensor's measurements is a challenge that a realistic solution has to deal with. In this paper we propose a decentralized approach to detect diffuse event sources in dynamic and noisy environments, using a Wireless Sensor Network infrastructure and following a gradient-based strategy.
