EEDF: Energy-Efficient Data Forwarding in Autonomous Underwater Vehicle Aided UWSNS

Abstract

UWSNs are often used in places where continuous monitoring is needed, but people are not involved. Since these networks stay active for longer, they are expected to continue so. The sensor nodes in these networks, however, are restricted in their available energy resources (e.g., battery) other tough issues with UWSN include erratic energy usage, which creates energy gaps and therefore shortens network lifetime. According to a recent research, deploying AUVs significantly reduces multi-hop data transmission, thus increasing the energy efficiency of UWSN. Due to its constant mobility, the AUV is unable to maintain a connection with the UWSN's sensor nodes for an extended length of time. This means we introduce a new underwater routing protocol called EEDF (Energy-efficient data forwarding in AUV for UWSN). The AUV in the EEDF uses gateway nodes to collect data. Gateway nodes for communicating with the AUV are found among all nodes. The welcome packet's input values determine which gateway nodes are used. When a gateway node is completely fueled, this procedure occurs, converting a high-energy node into a gateway node. By selecting an adaptive gateway node, it balances energy usage and network lifespan. According to the research and NS-2 simulation results, mathematical analysis and EEDF outperform the timeslot approach in terms of energy cost and packet delivery ratio.
