Recent advances in scheduling transmissions for underwater acoustic networks utilize and exploit long propagation latency of acoustic waves for achieving throughput gain. These techniques utilize the propagation delay information of the considered network geometry and schedule transmissions in time slots. Time-slotted transmissions are such that most of the interference overlaps with the transmission...
The potential of exploiting large propagation delays in underwater acoustic (UWA) networks to maximize the network throughput is established in the recent past. Transmission scheduling strategies have been proposed to take advantage of large propagation delay. Super-TDMA is one among such Medium Access Control (MAC) strategies proposed. It is a form of Time Division Multiple Access (TDMA) protocol...
In a recent work, a regular grid-based network topology with multihop relaying was investigated. A transmission strategy which maximizes the throughput while exploiting the large propagation delay was presented, and the upper bound on throughput established. However, deployments of communication nodes in the ocean inevitably result in slight positional deviations from the expected locations of the...
Underwater acoustic communication networks face several challenges: large propagation delays, low bandwidth and high transmission power. Recent studies exploit the large propagation delay to allow concurrent transmissions in the network. Given a suitable network geometry, it has been shown that the network throughput increases linearly with the number of nodes, provided optimal transmission schedules...
