Abstract: In recent year Wireless sensor Network (WSN) are replacing the traditional industrial wired communication system. One of the major technical challenges in WSN is to provide reliable as well as efficient communication under fading channel. When IWSNs are deployed in a harsh industrial environment, the vulnerability of wireless signal leads to high risk of transmission failure which result in missing or delaying of process or control data. But in most existing solutions the traditional routing protocols, such as AODV, AOMDV, and DSR, may provide solution in the form of reliable protocol but these protocol suffer from less security and Denial of service. These solutions may find their limitations in industrial installations due to the harsh environmental conditions, interference issues, and other constraints which results in undesirable delay as well as additional energy consumption. To overcome these limitations new biased back off scheme is introduced in the route discovery phase to find a robust virtual guide path with low overhead which can provide more cooperative forwarding opportunities. Again, this motivates to provide better solution for above problem there is another protocol which extends AODV with R3E to increase its effectiveness and feasibility. The goal is to provide reliable reactive routing enhancement to increase the link dynamics for WSN and to increase reliable and energy efficient packet delivery against unreliable wireless link.. And provide solution to reliable route discovery and efficient cooperative forwarding problems which can effectively improve robustness, end-to-end energy efficiency, and latency. Simulation results showed that, as compared with other protocolsAODV-R3E can effectively improve robustness, end-to-end energy efficiency and latency. Now days AODV-R3E has worldwide attention for use in different applications.
