Resource allocation scheme for underwater acoustic communication system with wireless charging
摘要
Abstract
To improve the communication rate of the underwater acoustic communication systems and solve the power supply problems better,a resource allocation scheme for underwater acoustic re-lay amplification and forward communication system was proposed.The sonar relay of the system was equipped with wireless charging device,obtaining energy from the base station to amplify and forward the signal from the base station by time-division-multiple-access.A near optimal time slot resource allocation strategy was deduced for charging and the communications between each sensor under water by using the Lagrange optimization algorithm to maximize the boundary of channel erg-odic sum-throughput.The simulation focused on different channels,transmit powers and communi-cation distances,respectively.The results show that compared with conventional allocation strate-gies,the proposed allocation strategy can improve the boundary of the channel ergodic sum-through-put,thus improving the throughput and the efficiency of the system.关键词
