位置信息辅助的机间自组网路由协议研究

[摘要] 提出了一种适用于机间自组网的路由协议算法，该算法使用位置信息辅助计算节点间的链路持续时间，并以此链路持续时间作为拓扑稳定情况的预测。各节点则依据跳数最小原则和链路持续时间最长原则进行路由计算，并在条件允许的情况下，为网络中的节点建立两条路由。仿真结果表明，该算法能够满足机间自组网的高动态拓扑变化，提供良好的网络性能。

[Abstract] In this paper, an aircraft mobile ad hoc network (MANET) routing protocol is proposed. In this routing protocol, a new link parameter called link duration is computed according to the locations of aircraft and is used to forecast the stability of a wireless link. With the link duration, path duration can be obtained between any two nodes. A node computes each routing entry, satisfying both the least hops and longest path duration and finds another point disjoint path if possible. The simulation results show the routing protocol can adapt to network topology and improve network performance.
