摘　　要：水下传感网络采用声波进行通信,具有长时延、高错误率和低能耗要求等技术挑战。为此,提出基于节点权重的地理位置路由(weight of node-based routing,WNBR)。在WNBR路由中,当源节点需要转发数据包时,依据深度适度因子构建候选下一跳转发节点集,利用节点剩余能量、距离和链路质量信息计算下一跳转发节点集中每个节点的权重。最后,选择具有最大权重的节点作为源节点的下一跳转发节点。仿真结果表明,提出的WNBR路由能够有效均衡能耗,降低端到端时延,提高了数据包传递率。Underwater Sensor Networks(UWSNs)adopts acoustic communication,characterized by high delay,high error rate and low energy-consumption requirement which lead to great challenges for UWSN communication. Therefore,weight of node-based routing(WNBR)is proposed in this paper. In WNBR protocol,source node determines the candidate forwarding node set by depth fitness factor of neighbor nodes. Then the weight of nodes is computed by resduial energy,distance and quality of link.Finally,the node with maximum weight is considered to be next-hop forwarding node.Simulation results show that the proposed WNBR can effectively balance energy consumption,reduce end-to-end delay,and improve the packet delivery ratio.
