摘　　要：从均衡消耗网络节点能量的角度出发,提出了一种考虑能量的自组网概率路由协议(Energy-Aware Probability Routing,EAPR)。EAPR在DSR(Dynamic Source Routing)路由发现过程中引入了概率模型,隐式地均衡通信流量,进而均衡消耗网络各节点能量。对概率模型中的系数α进行了分析,并使用仿真验证了系数α对于EAPR性能的影响。基于仿真结果对EAPR和LEAR(Local Energy-Aware Routing)进行了比较和分析。This paper proposes an energy-aware probability routing protocol for MANETs （EAPR） to balance the energy consumption among the nodes. EAPR introduces a probability model in the route discovery procedure of dynamic source routing （DSR）. It implicitly balances the communication traffic and further achieves balanced energy consumption among all the nodes. It analyzes the coefficient α in the probability model and illustrates its effect on EAPR through simulations. Also the comparisons between EAPR and the local energy-aware routing （LEAR） and the analysis are given on the simulation results.
