English abstract
In this research, we developed a new broadcast protocol for UWSN called Three Dimensional Broadcast Protocol for Underwater Wireless Sensor Network (3D-BUWSN). 3D-BUWSN tries to achieve high reachability rate, less energy consumption and good end-to-end delay. All sensors are deployed in 3D space at different depth equipped with localization service to determine position of the sensor node in the network. To avoid broadcast storm problem, 3D-BUWSN privileges the re-broadcast operation to the farthest nodes from the forwarder.
3D-BUWSN has been evaluated through developing a simulation model in Aqua-Sim simulator which is used to evaluate underwater sensor networks. We compare its performance with Vector-Based Forwarding as Broadcast (VBFB) and Probability-based method. The simulation results show that 3D BUWSN is the best in achieving higher reachability compared to VBFB and Probability-based methods. In terms of both consumed energy and end-to end delay, 3D-BUWSN and probabilistic approach are close. VBFB shows better consumed energy but at the cost of high end-to-end delay and low reachability.
