摘要
水下无线传感器网络通信受环境影响,造成网络的能耗大、数据传递率低、时延大,提出了AE-VBF路由协议。该协议在VBF协议基础上进行了优化,选择候选节点时引入能量预警值并改进转发因子,考虑了节点的能量信息和位置信息,同时引入了路由管道半径算法。通过仿真分析,AE-VBF协议随着网络密度的增加,以较小的数据包传递率的降低为代价,减少了网络的能量消耗,均衡了网络的整体能耗。
The communication of underwater wireless sensor networks is influenced by environment,which results in high energy consumption,low data transmission rate and longtime delay.AE-VBF routing protocol is proposed,which is optimized on the basis of VBF protocol.AE-VBF protocol introduces energy warning value and improves desirable factor when selecting candidate nodes,considers energy information and location information of nodes,and introduces routing pipe radius algorithm.Through simulation analysis,AE-VBF protocol reduces the energy consumption of the network and balances the overall energy consumption of the network with the increase of network density,at the expense of smaller packet delivery rate.
