Decentralized Control Algorithm for Fast Monitoring and Efficient Energy Consumption in Energy Harvesting Wireless Sensor Networks

Abstract

The paper proposes a fully decentralized algorithm to control nodes transmission radii for simultaneously coping with energy-type requirement (e.g., network power consumption) and application-type requirement (e.g., fast monitoring and estimation of variables of interest). The stability of the closed loop network under the proposed control law is proved. Simulation validations show the effectiveness of the proposed approach in nominal scenario as well as in the presence of uncertain power requirements and harvesting system supply, outperforming a well known related approach existing in the literature.
