Abstract: Despite being a fundamental networking primitive, data broadcasting
has so far received little attention in the context of underwater networks.
This paper proposes an adaptive push system for data broadcasting in underwater
acoustic wireless networks with locality of client demands. The proposed system
exploits the characteristic relationship between the bandwidth of an underwater
acoustic link and the transmitter-receiver distance in order to improve
performance in environments with locality of client demands. Simulation results
show superior performance of the proposed approach in the underwater
environment compared to existing systems.
