一种新的航空自组网混合路由算法

Aeronautical Ad hoc Network Hybrid Routing Algorithm

路由算法是航空自组网研究的重点和难点。针对目前对航空自组网高动态路由研究较少的现状,考虑到飞机节点高动态但局部结构相对稳定的特点,通过将ADS-B系统整合到路由表建立过程中,设计了一种基于分簇和地理位置信息的混合路由算法CGCR。应用ADS-B消息中的节点位速和飞行意向数据预测节点运动趋势,从而选择最优下一跳节点。通过扩大下一跳选择区域策略来避免路由空洞的产生。仿真结果表明,CGCR具有良好的性能。

Routing algorithm is the key and difficult point in aeronautical ad hoc network（AANET）research.Due to the current situation of few studies in AANET routing of high dynamic and the characteristics of high dynamic but relatively stable local structure of the aircraft node,a hybrid routing algorithm based on clustering and geographic information（CGCR）was proposed by integrating the ADS-B system into the process of establishing the routing table.The algorithm uses node bit rate and flight intention data in ADS-B message to forecast node movement trend in order to select the optimal next hop.And it expands the selection area in next hop to avoid the generation of routing voids.Simulation results show that CGCR has good performance.
