摘要：Due to the use of acoustic channels with limited available bandwidth, Underwater Sensor Networks (USNs) oftensuffer from significant performance restrictions such as low reliability, low energy-efficiency, and high end-to-endpacket delay. The provisioning of reliable, energy-efficient, and low-delay communication in USNs has become achallenging research issue. In this paper, we take noise attenuation in deep water areas into account and propose anovel layered multipath power control (LMPC) scheme in order to reduce the energy consumption as well as enhancereliable and robust communication in USNs. To this end, we first formalize an optimization problem to managetransmission power and control data rate across the whole network. The objective is to minimize energy consumptionand simultaneously guarantee the other performance metrics
