Optimized Routing in WSNs: Pragmatic Review and Research Direction
Soni Chaurasia, Kamal Kumar · 2022
In WSNs, the most crucial matters for the research are extending the network's lifespan and improving energy efficiency. Therefore it is essential to provide an energy-efficient method for overcoming the challenges associated with optimized routing protocols for forwarder node selection. The forwarder node selection is an integral part of the process. This survey paper offers an overview of meta-heuristic techniques for minimizing energy consumption by evaluating optimized routing protocols. Here we compare opportunistic routing protocols such as ExOR, SOAR, EEOR, ENSOR, EEOR-FL, NA-TORA, ARIOR, QoS-aware OR and BOR. The use of opportunistic routing improves the efficiency, accuracy, and dependability of sensor networks. Moreover, we analyze the state-of-the-art meta-heuristics opportunistic routing protocols such as DyMORA, BMOOR, EBAR, EESCP, FPU-DA, EPO-BES, and CORP.A detailed analysis of the related methods is performed, and conclusively, the paper ends with guidelines for the forthcoming research on the energy efficiency platform/directions in WSNs.
