摘要 水下声信道是一种复杂信道,由于各方面因素影响,在数据传输过程中,水下传感器网络数据链路层会有可能产生随机中断。研究了一种虚拟汇聚节点的多路径水下传感器网络路由技术,在随机布设的传感器节点中选取了缓存节点,并创建了局部的汇聚节点,通过多路径的路由技术,有效减少了网络吞吐率受链路中断的影响,并且避免了汇聚节点处的数据冲突。通过网络的冗余性,增强了网络稳定性、鲁棒性。 Underwater acoustic channel is a complex channel, due to effect of various factors, data link layer of underwater sensor networks(UWSNs) would be broken off randomly. Research a muhipath routing technology of UWSNs based on virtual sink node, and some cache nodes is selected from randomly distributed nodes, and local sink nodes are created. By multipath routing technology, effect of data link interrupt on networks throughout is reduced effectively, and conflicts in sink nodes can be avoided. The stability and robustness of networks is enhanced by network redundancy.
