| 摘要 |
在基于水下网络节点均匀分布的前提下 ,通过结合传输衰减和射线模型仿真水下通信信道 ,推导得出水下传感器网络路由中端到端平均误码率(BER)和网络节点分布密度之间的关系式。并且通过 Monte Carl o仿真方法 ,单跳链路之间采用 MFSK通信方式 ,仿真了网络通信性能与节点分布密度的关系。通过仿真结果 ,可以预测水下网络在特定网络拓扑结构中网络整体的通信能力;而且能够在预先给定要达到的网络通信能力的约束下 ,得到最优的网络分布密度;这将为水下网络节点布放的同时衡量网络通信性能提供很好的参考价值。 |

I n this paper, the study on the relati on bet ween the communicati on perfor mance and node distributed density in Under water Sens or Net works (US N ) was p resented . The method combined the models of trans mitting l oss and ray of under water acoustics t o deduce the relati onshi p bet ween communicati on performance and node distributed density in US N.
Moreover, the conclusi on was si mulated byMonte Carl o methods . By the result of si mulati on, the communicati on ability of under water net work can be forecasted on the given node dep l oyment, further more the op ti mum net density will be found with the constraint of the given communicati on ability of under water net work, which affords benefit for the t opol ogy and node dep l oyment based on the communicati on performance in under water sensor net works . |
