An Adaptive Transmission Control Mechanism for Underwater Acoustic Sensor Network
An adaptive transmission control mechanism for underwater acoustic sensor networks is proposed in this paper. This mechanism controls transmission delay and releases collisions adaptively according to different topologies and the bit error rates of the wireless links periodically feedback by the receiver. Our work succeeds in releasing collisions and reducing propagation delay. Further more, the energy is saved by reducing repeated transmission. Simulations show ATC adapts the transmission time to the wireless link quality dynamically and saves about 50% energy when bit error rate is high.
