| Abstract: | Underwater Acoustic Sensor Networks (UW-ASNs) is made up of hundreds to thousands of underwater sensors, which communicate with each other via acoustic links. However, it is accordingly confronted with some problems like long propagation delays, high transmission power consumption, and limited available bandwidth and so on. This particular situation makes it possible, that multiple packets concurrently propagate in the underwater acoustic channel and it will improve the overall throughput of the network if we dispose in order. Based on this, we propose an Efficient Transmission Scheduling (ETS) algorithm, which makes the UW-Sensor nodes to increase the possibility of concurrent transmissions and reduce packet collisions happening according to the information of themselves. Simulations further validate that ETS outperforms existing solutions and has a better performance with the consideration of fairness. |
