摘　　要：针对Ad hoc网络中的路由协议通常采用基于数据路径最短的标准选路,而缺乏对网络负荷这一重要因素进行考察,这最终导致所选择的路径可能产生拥塞,并使某些过载节点寿命降低,提出一种根据节点的网络负载进行自适应路由选择的协议(ADMAR)。该协议把网络当前的动态负荷因素纳入考虑的指标,在节点选路过程中选择负荷较轻的路径,以达到合理地分担网络中负荷的目的。通过基于OPNET的仿真实验对该协议的性能和效果进行分析评估,实验结果说明ADMAR具有较好的负荷分担能力,并尽可能降低网络热点区域产生的可能性。Most of Ad hoc routing protocols select route based on the metric of shortest path first mechanism,which do not take network load into consideration.This may lead to congestion occur in the selected path.Correspondently,the lifetime of the loaded nodes will be reduced.This paper put forward an adaptive dispersive mobile Ad hoc routing protocol（ADMAR）,which took the index of dynamical load of current network into consideration.A node in network selected the path based on the network load reasonably.This could lead the whole network become load balanced one.Finally,this paper also evaluated this novel protocol through OPNET based simulation.The simulation shows that ADMAR can reduce the possibility of occurrence of network hotspot area.
