摘要:

水下无线传感器网络具有能耗大、数据传输效率低、拓扑结构动态变化的特点。针对水下环境中节点的移动优势,提出基于矢量和能量的路由协议。从源节点到汇聚节点建立矢量,根据候选节点到该矢量的距离确定优先级。在考虑距离的同时结合候选节点的剩余能量以确 定其是否成为最佳下一跳节点。仿真结果表明,与VBF协议和LB-AGR协议相比,即使无法知晓节点的地理位置,该协议在交付率、平均端到端延时和能耗方面仍可获得较好的结果。

Abstract:

Underwater Wireless Sensor Network(WSN) has the characteristics of high energy consumption,low efficiency of data transmission,dynamic topology.Aiming at the mobility advantage of nodes in the underwater environment,this paper puts forward a Vector and Energy based Routing(VER) protocol.This protocol builds a vector from the source node to the sink node,then determines the priority according to the distance from the candidate node to the vector.Considering the distance,the remaining energy of the candidate nodes is combined to determine whether it becomes the best next hop node.Simulation results show that compared with VBF protocol and LB-AGR protocol,the algorithm achieves satisfactory results in terms of delivery rate,average end-to-end delay,and energy consumption even if the node’s location is not known.

Key words: underwater Wireless Sensor Network(WSN), routing protocol, dynamic topology, vector, residual energy
