摘要:
在高速移动节点组成的空中交通网络中,节点的高速移动会增大路由路径中断的概率,进而增大重路由的频率,使网络的通信性能下降。选择可用度较高的链路生成路由路径,能够有效降低重路由频率,提高路由路径的可用时间。文中提出了一个将航空自组织网络的节点移动特征和链路可用度相结合的拓扑控制机制,并将该机制与OLSR协议结合,生成新的路径链接可用度路由协议(LAR协议)。通过仿真实验对比不同场景下LAR协议与其他路由协议的性能,包括端到端延迟、路径可用性及路径长度,结果表明,LAR协议可明显增加路径的可用时间,同时端到端延时和路径可用率2项指标的性能也较为理想。

Abstract:
In an air traffic network consisting of fast-moving nodes, their fast movement increase the possibility of a routing path break, thereby increasing the re-routing frequency and reducing the communication performance of the air traffic network. Selecting a link with high availability to generate a routing path can not only reduce the re-routing frequency effectively but also increase the lifetime of the routing path. This paper proposes a network topology control mechanism that combines node movement characteristics of aeronautical ad hoc networks with its link availability. In addition, the control mechanism is combined with the OLSR protocol to generate a new link availability routing (LAR) protocol. Through simulation, the LAR performance is compared with other routing protocols in different scenarios, including the comparison of end to end delay, path availability and path length. The simulation results show that the LAR protocol can significantly increase the lifetime of routing path compared with the topology-based routing protocol and location-based routing protocol and that the performance of end to end delay and path availability is desirable.
