摘　　要：水下传感器节点随水流移动,导致网络拓扑高度动态,这给水声无线传感器网络路由协议带来了挑战。为了解决水下传感器节点移动和能量受限给传统路由协议带来的挑战问题,提出了基于距离预测与多准则决策的水声网络分层路由协议。在预测节点间的距离预测阶段,该协议提出基于改进灰色预测模型的灰色马尔可夫节点间距离预测模型,并根据该模型预测结果给出了有效邻居节点确定规则;此外,提出基于多准则决策的灰色关联分析模型来计算邻居节点的灰色关联度,选择灰色关联度最高的邻居节点作为最佳下一跳。通过NS3网络仿真模拟器进行了大量的仿真实验。结果表明,基于距离预测与多准则决策的水声网络分层路由协议在提高数据交付率、降低端到端延时和能耗等方面较LEER、DBR、VBF、LRNMP和IATLR协议具较大的优势。Underwater sensor nodes may move with the water current,resulting in a highly dynamic network topology,which brings about challenges for the routing in underwater acoustic network(UAN).To cope with the challenges of node mobility and energy efficiency in UAN,this paper proposed a distance prediction and multi-criteria decision based layering routing for underwater acoustic networks(DMDLR).To predict the distance between nodes,this paper presented a gray Markov inter-node distance prediction model based on an improved gray prediction model.According to the prediction results based on the gray Markov distance prediction model,it provided an effective neighbor node determination rule.Further,it proposed a grey relational analysis model based on multi-criteria decision to calculate the grey relational degree(GRD)of neighbor nodes,and selected the neighbor node with the highest GRD as the optimal next hop.It conducted extensive experiments with the NS3 network simulation simulator to evaluate the performance of the DMD-LR protocol.The results show that the DMD-LR protocol has great advantages in improving packet delivery rate,reducing end-toend delay,and lowering total energy consumption compared with the LEER,DBR,VBF,LR-NMP,and IATLR protocols.
