Abstract
移动Ad hoc网络路由质量受到很多因素的影响.目前,多数移动Ad hoc网络路由协议利用单一跳数或其他基准作为路由产生的判据,使得协议整体性能的改善比较困难.提出一种考虑节点能量、通信干扰、丢失率和移动性(energy, interference, communication drop rate and mobility,简称EIDM)的综合选路基准.使用自适应权重,该基准能够根据网络状态调节各因子的作用.模拟实验结果显示,EIDM很好地减缓了热点效应.;Routing quality is affected by several factors altogether in mobile ad hoc networks (MANET). Most of current MANET routing protocols utilize hop count or other metric as their route creation criteria, which makes it hard to improve the overall protocol performance. This paper proposes an integrated routing metric which takes energy, communication interference, drop rate and mobility of a node (EIDM) into consideration. With an adaptive weight, this metric can adjust its stress on different items according to the network condition. Simulation results show that the EIDM does well in mitigating the hotspot effect.
