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.
Highlights
Wireless Industrial Sensor Networks are networks Industries require incessant monitoring and control to facilitate sound operation at various tactical environmental conditions
Some of the Wireless Industrial Sensor Network (WISN) applications include, process monitoring and control, process data such as pressure, humidity, temperature, flow, level, viscosity, density and vibration intensity measurements can be collected through sensing units and transferred wirelessly to a control system for operation and management (Zhao, 2011)
The first standard energy efficient protocol is Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol was proposed by Heinzelman et al (2000) for clustering in wireless sensor network
Summary
Wireless Industrial Sensor Networks are networks Industries require incessant monitoring and control to facilitate sound operation at various tactical environmental conditions. The flow of information from the sensor nodes to the base station needs to be reliable, rapid and less energy consuming. By incorporating these features into a WISN, it is possible to improve the network lifetime and efficiency to a good extent. The main challenges involved in the design of a reliable protocol for WISN are:. Energy consumption of the nodes is to be kept very low. Routing for Real-Time and Reliable Communication in Wireless Industrial Sensor Networks. The protocol estimates the expected energy cost and delays along with the reliability of the nodes successively that form the path to the base station.
