Abstract

Wireless Industrial Sensor Network (WISN) is the heart of automation and control in industrial monitoring. Live updates about situations at hostile areas of the industry are reported to a base station frequently to enhance harmless functioning of the network. EARQ was proposed to enhance the routing operations for wireless industrial sensor networks. It provides real-time, reliable delivery of a packet, while considering energy awareness. In EARQ, a node estimates the energy cost, delay and reliability of a path to the sink node, based only on information from neighboring nodes. The expected energy cost measurement does not provide accuracy; hence the relative energy cost is measured to enhance the lifetime of the WISN while also enhancing the routing reliability in the Enhanced EARQ (EEARQ) protocol proposed in this study. Simulations in the network simulator are used to justify the proof of the enhancement.
