An Energy Conservative Routing Path Discovery Algorithm in Wireless Nano-Sensor Networks

Abstract

Finding suitable routing paths in Wireless Nano- Sensor Networks (WNSNs) is a fundamental problem to be solved for energy-efficient communication in Internet of Nano- Things (IoNT) applications. Due to the nano- batteries having very limited capacity, the nano-sensor nodes should communicate through an energy-efficient routing scheme on the network. Therefore, the routing algorithms developed for WNSNs should save more energy while the nano-sensors are transmitting data packets to the base station. Therefore, in this paper, an energy- conservative routing path discovery algorithm between a nano-sensor node and the sink node is proposed for IoNT applications. According to the results, the proposed algorithm successfully builds the energy-conservative paths by up to 90.3 %, saves energy on each route by up to 98.857 nJ and prolongs the lifetime by up to 5.842 times on average regarding the shortest path and hop count routing between a nano-node to the sink node. © 2023 IEEE.
