Network Lifetime Aware Routing Algorithm for Energy Harvesting Wireless Sensor Networks

Energy Harvesting Wireless Sensor Network (EHWSN) technology has arrived for the extensive urgency of preventing the sensor nodes’ battery limitation to develop a sustainable network system. Therefore, prolonging network lifetime through distributing the data transmission burden on sensor nodes is a significant challenge in WSNs. In this paper, we have proposed a hierarchical system framework and a lifetime aware data routing algorithm. The proposed algorithm distributes the data routing loads to the relay nodes across the network with a high energy harvesting rate. Extensive simulation experiments have been carried out in MATLAB to study the performances of the proposed algorithm compared to the existing works in terms of network lifetime and data packet delivery ratio.
