Topology Control For Depth Adjustment Using Geographic Routing In Underwater Wireless Sensor Networks

In the recent years, Underwater Sensor Network (UWSN) is treated to be the best suited brain storming technology to inspect the oceans using marine wireline communication. The UWSN has limited data gathering process due to the individuality of acoustic communication. Routing protocols are used in UWSN which helps to improve the data collection by its individuality of acoustic communication with its dynamic network topology. In this paper, Geographic and opportunistic routing with Depth Adjustment based topology control for communication Recovery over void region (GEDAR) is proposed. It uses the greedy opportunistic forwarding to broadcast the data packets from each sensor nodes to multiple distinct sinks at the sea level. If the node persists in the communication void region, then this opportunistic protocol advances one step forward to the recovery mode procedure. The utilization of this evolving procedure can automatically manages the depth adjustments of the void nodes rather than using the control messages to discover the routing paths. The experimental result shows that our proposed routing protocol GEDAR outperforms the best amidst other routing protocols by varying network density and traffic load.
