A decentralised routing algorithm for time critical applications using wireless sensor networks

Abstract

Wireless Sensor Networks (WSN) are presently creating scenarios of decentralised architectures where application intelligence is distributed among devices. Decentralised architectures are composed of networks that contain sensors and actuators. Actuators base their action on the data gathered by sensors. In this paper, a decentralised routing algorithm called DRATC for time critical applications like fire monitoring and extinguishing is proposed that makes use of the Decentralised Threshold Sensitive routing algorithm. The sensing environment consists of many Monitoring Nodes that sense fire and report the data to the Cluster Head. The Cluster Head directs the Extinguishing Node to extinguish the fire before sending the data to the Base Station. © 2013 Springer-Verlag.
