一种空基自组网路由协议的研究

针对传统Ad Hoc路由协议无法满足空基自组网在高动态拓扑下成功投递、路由开销和低延迟的要求,研究了一种利用空基平台已规划的航线信息来提高网络路由性能的路由协议.该路由协议由已知移动信息路由协议（MARP,mobility aware route protocol）和移动信息洪泛协议（MDP,mobility dissemination protocol）组成.MARP利用规划的航线信息预测网络拓扑并计算路由,MDP采用洪泛方式通知网络中所有节点实际拓扑和预测拓扑的差异信息.设计该协议的数据结构、链路预测机制、实际链路探测机制、多余广播减少机制.通过QualNet仿真验证,结果表明,MARP/MDP在平均报文传输延迟、报文成功投递率及路由开销方面比AODV和OLSR协议具有更优越的性能.

Study on an Airborne Ad Hoc Network Routing Protocol

A new routing protocol is studied with regards to the problem that the traditional Ad Hoc routing protocol can＇t satisfy the requirements of Airborne Ad Hoc Network for packet delivery ratio, controling overhead and low latency which has highly dynamic topology. The planed airline information is utilized to improve the performance of network. The protocol includes Mobility Aware the Route Protocol（MARP） and Mobility Dissemination Protocol（MDP）. MARP utilizes the planned airline information to predict network topology and calculate router. MDP tells all nodes the difference among the real and predicted topology by flooding. The data structure, link prediction mechanism, real link detection mechanism and reducing redun- dant broadcasting mechanism are designed. The simulation results show that MARP/MDP has better perform- ance than AODV and OLSR protocol in packet delivery ratio, end-to-end latency and control overhead.
