Utilizing Locality of Demand for Lower Response Times in Underwater Data Broadcasting

Despite being a fundamental networking primitive, data broadcasting has so far received little attention in underwater networks. This paper proposes an adaptive push system for data broadcasting in underwater acoustic wireless networks with locality of client demands. It achieves adaptation of its broadcast schedule according to the a-priori unknown needs of the clients, it efficiently combats the problem of high latency of the underwater acoustic wireless environment and it exploits the bandwidth distance relationship of this environment in order to improve performance in topologies with locality of client demands. Simulation results show superior performance of the proposed approach compared to existing systems.
