Systematic Analysis and Review of Path Optimization Techniques in WSN

Abstract

Wireless Sensor Network (WSN) is a centre of research owing to prevalent applications like military and scrutinizing circumstances of environment. The recent approaches showed that the mobility of sink in a controlled path can enhance the efficiency of energy in WSN, but the constraints of the path make the routing more complicated. Thus, the sink with fixed speed poses less communication time for collecting data via sensor nodes that are arbitrarily deployed. This limitation has noteworthy issues in enhancing data collected and minimizing energy consumption. Moreover, these research constraints led to the design proficient path optimization technique in WSN. This work presents a survey based on path optimization strategies. In addition, a thorough investigation is done based on various parameters. Also, we have analyzed the merits and demerits of conventional path optimization strategies. Finally, future research directions in obtaining efficient path optimization in Wireless Sensor Networks along with the mobile sink are elaborated.
