说明：  能源问题对于移动自组网是非常重要的,因为移动节点只能依靠它们有限的电池供应。原先的路由算法中,选路时不 考虑节点的剩余能量,选定了一条路由后就一直用下去,直到数据传完或拓扑变更引起重选路由
(Energy issues for the mobile ad hoc network is very important, because the mobile node can only rely on their limited battery supply. The original routing algorithm, routing node does not consider the remaining energy, selected after a route has been used until data transmission End or topology changes caused by routing re-election)
