摘　　要：提出了一种权衡分集和复用MIMO技术的水下传感器网络节能算法.设计了水下传感器网络信号传播模型,实现了MIMO复用和分集折衷的节能方案.基于MATLAB进行了算法的仿真实验,对比了此算法和MIMO全分集、MIMO全复用算法的性能.结果表明,提出的算法在保证了传输可靠性的基础上实现了节点能耗降低,延长了水下传感器网络的生存时间,提高了传输速率、降低了误码率.In this paper, we propose an energy-efficient algorithm for which weighs the diversity and multiplexing of MIMO technology. We design the signal propagation model of UWSNs , and realize an energy-efficient solution based on the tradeoff between multiplexing and diversity of MIMO. Finally, we conduct the simulation experiment by MATLAB, then compare the performance of three algorithms, which are MIMO full diversity, MIMO full multiplexing and MIMO based on the tradeoff diversity and multiplexing. The simulation results show that the proposed algorithm in guarantee the transmission reliability on the basis of reducing the energy consumption, and prolong the survival time, enhance the transmission rate and reduce the bit error rate of UWSNs.
