A Brief Review of State-of-the-art Routing Methods in Wireless Sensor Network

Due to the widespread use in recent decades, wireless sensor networks (WSNs) have emerged as a top research area. However, the dynamic reconfiguration of WSNs offers a significant hurdle due to the fact that conventional methodologies conFigure WSNs statically. Clustering methods can be implemented in WSNs to overcome this difficulty. A plethora of researchers have proposed routing methods based on the concepts of clustering. In this paper, a brief review of state-of-the-art routing methods is presented. The focus of this work has been on the selection of Cluster Head (CH) adopted by recently proposed studies that use different optimization methods. Hence, this study will help the researchers to propose new parameters for selecting the CH that can enhance the network lifetime.
