摘　　要：自组网是由一组带有无线收发装置的移动节点纽成的一个能够支持多跳的临时性的计算机通信网络,大多数节点是 由有限寿命的电池来提供的,因此能量保护策略成为设计该类网络路由协议的一个重要依据．同时,拓扑的动态变化是该类网 络的另一主要特征,它将影响路由的稳定性．通过对节点当前剩余电池能量和邻居节点之间链路稳定性的观察,并使用模糊逻 辑控制策略,文中提出了一种基于动态源路由的自适应路由协议,仿真表明该协议有效地延长了网络的生存时间,并提高了报 文提交率．Ad hoc network is a temporary multi-hop wireless computer communication network that is composed of mobile hosts communicating with each other through wireless links. Efficient energy conservation plays an important role in the performance of Ad hoc network routing because mobile nodes in such networks are usually battery-operated. Dynamic topology is another typical characters. It impacts the stability of route. By observe the remaining energy of node and stability of link between neighbor node, apply a fuzzy logic system to route discovery processes, this paper presents a DSR-based adaptive routing protocol. Simulations clearly indicate that the proposed protocol prolongs the lifetime of network and at the same time improves packet delivery.
