基于通信网络算法在水下通信中仿真研究

研究通信网络在水下通信效率优化问题,由于海洋的复杂环境、水声不稳定以及水声受到介质噪声的干扰,造成水下通信率低。为了解决上述问题,建立了一种H∞滤波器节点移动预测算法的资源预留机制,为节点在水声网络中提供基于移动IP的QoS保障。根据移动节点的移动方向判断其即将加入的子网,在子网中提前预留资源,其它子网不再为移动节点提前预留资源,从而节约水声无线通信网络有限的带宽、能量等资源,并进行仿真。仿真结果表明,改进的方法能够为水声网络提供较高的资源利用率,在时延、吞吐量等方面提供有效保障。

Research on Mobile IP Management Technology Based on QoS Guarantee for Underwater Acoustic Network

Research a mobile IP based on QoS guarantee management technology for the underwater acoustic communication network.Because the marine environment is complex,acoustic wireless link is unstable and because of the acoustic network dynamic topological properties,the paper proposed a mobile IP management technology based on the reserve mechanism of H∞ filter node movement prediction algorithm.According to the movement direction of the mobile node,its accession subnet was judged and the resources were reserved for the node in this subnet,the other subnets did not reserve resources for the mobile node in advance,so that we can save the limited bandwidth,energy and resources in underwater acoustic wireless communication network.The simulation experiment results show that the technology can provide higher resources utilization for the acoustic network,and guarantee the time-delay and throughput.
