【摘要】 水下声信道是一个极其复杂的信道,它对网络性能的影响很大。在采用位置信息作为依据选择路由的机制中,忽视恶劣的水下声信道对网络性能的影响造成大量数据重传,能量利用率低,网络生存期短。针对这个问题提出了一个基于链路质量估计的路由算法,通过历史记录估测当前信道传输状况作为路由选择的依据。仿真结果表明该算法能显著减少数据重传,提高能量利用率,延长网络生存期。更多还原

【Abstract】 Application characteristics of underwater acoustic sensor networks make it a remarking characteristic to utilize node’s residual energy efficiently to prolong the network lifetime.In the paper an energy-efficient and reliable routing protocol is present basing on estimating quality of link.The proposed protocol prolongs the network lifetime by energy sensing,and it achieves expansibility.Simulation results show that the proposed protocol has good expansibility in the underwater acoustic networks.更多还原
