通过分析Ad Hoc网络的特点及其对应的井下巷道工作面的系统方案。以典型的两种按需路由协议AODV与DSR为例,在不同移动节点密度下使用NS2网络仿真软件的Random Way-point Mobility Mode模式,选取数据分组投递率、端到端的平均延时、平均跳数、路由开销这4个性能指标对路由协议进行了仿真,结果表明Ad Hoc网络中的移动节点密度总是存在一个最佳范围,AODV路由协议为20-35,DSR路由协议为25-35,使网络的各种性能指标具有较好的鲁棒特性,对井下实时监测网络的应用需求具有现实的指导意义。
By analyzing the characteristics of Ad Hoc network and its corresponding system plan of mine roadway working face. Taking the typical two kinds of on-demand routing protocols AODV and DSR as an example, we use the Random Way-point Mobility Mode of NS2 network simulation software at different mobile node densities to select the data packet delivery rate, the average end-to-end delay and the average hop The results show that there is always an optimal range of mobile node density in Ad Hoc networks. The AODV routing protocol is 20-35, the DSR routing protocol is 25-35, Make all kinds of network performance indicators have good robustness characteristics, and have realistic guiding significance to the application requirements of underground real-time monitoring network.
