摘要
针对水下通信存在延迟大、能量供应有限、误码率高等问题,提出了基于层级的水声网络自适应地理路由协议(LB-AGR)。各个传感器节点通过网络初始化获得自己的层级信息;在传输数据阶段基于层级、剩余能量和节点密度等信息在邻居表中计算最佳的下一跳邻居节点进行转发。仿真结果表明,LB-AGR路由协议在能量消耗、端到端延时、交付率等方面具有优良的性能。
In view of the problems of large delay,limited energy supply and high error rate in underwater commu-nication,this paper puts forward the layer-based adaptive geographic routing protocol(LB-AGR)for underwater a-coustic networks.Each sensor node obtains its own level information through network initialization.In data transmis-sion stage,each receiving node calculates the best next hop node in the neighbor table for forwarding based on infor-mation such as level,remaining energy and node density.Simulation results show that the LB-AGR routing protocol has excellent performance in terms of energy consumption,end-to-end delay,and delivery rate.
