A New Energy Efficient and Depth based Routing Protocol for Underwater Sensor Networks

Due to certain conditions of underwater environment, providing an efficient and scalable routing protocol in underwater acoustic sensor networks (UWSN), has many challenges. Communication in UWSNs is done through sound that compared with radio; it has lower speed, higher bit error rate, smaller bandwidth and higher and variable propagation delay. Also, in UWSNs, improving the energy efficiency is one of the most important issues since replacement or recharging of nodes batteries has a high cost. Moreover, many proposed routing protocols for UWSNs, use full information about the position of the nodes, that obtaining this information is a fundamental challenge in these networks. In this paper, a new protocol is proposed in which only the depth information of the nodes used in the routing process. Also, to balance the overall energy consumption and thereby increase the network lifetime, residual energy of the nodes considered in the routing calculations. The protocol is compared with DBR protocols using NS2 simulator. Our simulation results show that the proposed method not only improves the overall energy consumption of the network, the end-to-end delay is also reduced.
