摘要
针对井下无线信道干扰严重、节点能量有限的特点,提出了一种基于误码率和能量约束机制的井下无线自组织网络自愈AODV路由协议,并采用NS2仿真工具进行了建模仿真。仿真结果表明,改进的AODV路由协议在数据包成功接受率上略高于AODV路由协议,较大幅度地减少了路由负担,有利于节省网络能量。
In consideration of characteristics for the serious interference in underground wireless channels and the limited energy of nodes,the authors proposed a self-healing AODV routing protocol based on error rate and energy constraint mechanism,made a modeling simulation with the simulating tool of NS2.Simulation result showed that the improved AODV routing protocol had a slight improvement in terms of package delivery,and was enhanced greatly in routing load.Therefore,the improved AODV routing protocol decreased the routing load greatly,with the advantage of reducing the energy consumption of wireless network.
