Robust and efficient routing in three-dimensional underwater sensor network

Abstract

Three-Dimensional (3D) Underwater Wireless Sensor Networks (UWSN) different from the terrestrial Network forms various challenges like propagation delay, battery, packet loss. Sensor deployed in water is mobile and hence is the prominent challenge while transferring the data packet. Various routing protocols have emerged but still finding a static and reliable route remains a foremost challenge. We propose Robust and Efficient Routing Protocol (RERP) attaining a more static route for the communication between two nodes. In RERP, we assign a rank to each node by formulating important aspects of the sensor in order to form a stable network. So, by selecting least rank node for communication, a more efficient and reliable routing path is constructed. 2-Hop Acknowledgment along with the mobility factor also ensures high packet delivery ratio.
