Wireless sensor networks have large benefits in terms of flexibility, easy and fast installation and low cost. WSNs can be used in any environments for example Industrial wireless sensor a network (IWiSNs) which may have harsh environmental conditions, thus providing faithful and efficient communication is a big challenge. Lot of research work has happened to provide efficient mechanism for reliable packet transmission. In the traditional approach, when the node has data to be sent to sink, it first establish the path and then forwards the data, even though there are multiple paths, it uses shortest path. The energy level of nodes across this path drains which may lead to node failures, in turn failure of communication network. This work proposes reliable transmission and load balancing approach to improve network lifetime. Through extensive simulations, comparing with other routing protocols, [ESFTB] increases packet delivery ratio, with high energy efficiency.

INTRODUCTION A Wireless sensor networks can be defined as the network of devices, denoted by nodes which can sense the environment and also communicate each other and exchange the information gathered from the monitored area through the wireless links in the network. WiSNs are adapted in industries due to their several benefits over wired system like easy and fast installation and also low cost of maintenance. In IWiSNs[1] , the sensor nodes are scattered and are deployed to sense the surrounding and transmit the sensed information over the distances that depends on the application of these sensor nodes. The wireless channel conditions in industries is considered to be harsh due to varying temperature, high vibrations , interference issues and many other constraints. So, when sensor nodes deployed in such harsh environment the vulnerability of the wireless signals leads to transmission failure and also missing or delaying of process or control data which can be a loss in terms of money, time, and man power. However for industries, missing of process or control deadline is normally intolerable, which possibly terminate the industrial automation and finally resulting in loss. The traditional routing protocols like AODV [2], AOMDV [3] and DSR [4] have their limitations in industrial installations. The sensed information should be reliably and timely delivered to the sink node. It also requires that these networks operate for many years without replacing the batteries. Therefore, reliability, timeliness and also energy efficiency is important for proper functioning of IWiSNs. II. RELATED WORK There are many routing mechanisms in WSNs to transmit the data packets to the sink node. Before transmission of data the path must be established from source, which uses source routing protocols. Due to varying environmental conditions and energy levels of sensor nodes results in path breaks or node failure. So new path needs to be established which may consume more time and energy. To overcome these reactive routing protocols were introduced. Charles Perkins and Elizabth proposed AODV [2] reactive routing protocol. While repairing the broken links in the network AODV provides a quick response and also loop few routes. AODV does not store any routing information, but it discovers new path when necessary and from point of failure. Mahsk K. M. and Samir .R. Das proposed Ad-Hoc on Demand Multipath Distance vector reactive routing [3] for dynamic Ad-Hoc networks. It discovers multiple paths form source to sink node, which helps to find alternate new route in case of route failures, although it discovers multiple paths it uses only one path. Dynamic source routing[4] is also a reactive routing RESEARCH ARTICLE OPEN ACCESS
