摘　　要：在移动自组网中,减少移动节点电池能量消耗,延长网络总的使用时间,已经成为路由协议性能评价的重要方面。提出了一种新的路由选择度量,它综合考虑了节点负载及当前的剩余能量,试图通过路由机制均衡网络流量、保护网络中的低能量节点。结合此度量方式提出一种路由选择算法LBEAR(Load-Balanced&Energy-Aware Routing),仿真结果表明,该算法能够使节点能耗与负载的分布更为均匀,相比以前相关的路由算法有效提高了吞吐量。In MANET, saving node＇s energy and prolonging network＇s operated time have been important aspects to evaluate protocols＇performance. This paper proposes a new routing metric, which integrates load and remaining energy of a node, trying to balance the traffic load and protect the low-power nodes. The paper also proposes a new routing method called Load-Balanced and Energy-Aware Routing （LBEAR） based on the new metric. Simulation results show that the new method makes the energy dissipation and traffic load distribute more evenly and improves the network throughput efficiently by comparing with prior proposals.
