A novel probabilistic broadcasting strategy for UUV Ad Hoc Networks

A novel probabilistic broadcasting strategy (PBS) for UUV (Underwater Unmanned Vehicles) Ad Hoc Networks is proposed in this paper. The main objective is to increase the efficiency of broadcasting in UUV Ad Hoc Networks. The UUV nodes closer to the vector from the last hop node to the destination participate in broadcasting with higher probability. We describe PBS, implement it and evaluate its performance using NS-2 network simulator. Simulation results reveal that the proposed algorithm achieves better performance in terms of the average packet delivery fraction, average end-to-end delay and average energy consumption of each received packet, which is respectively compared with VBF.
