A directional airborne network consisting of nodes equipped with multibeam antennas is considered. These nodes use the frequency division duplex mode of communication. This allows formation of multiple routes between a pair of source and destination nodes, where every forward and reverse route completely overlaps. Each of these routes supports the bidirectional traffic. These routes are formed using the bidirectional ad hoc on-demand multipath distance vector (BAOMDV) routing protocol. In this article, we propose a local route repair scheme, called BAOMDV-LR, when these routes break due to node mobility. The proposed route repair scheme preserves the overlapping and link-disjoint (or node-disjoint) characteristics of the routes, while reducing the need for expensive route rediscovery. The proposed scheme significantly improves the overall network performance for bidirectional traffic (in terms of packet delivery ratio, end-to-end delay, and routing overhead) as compared to the BAOMDV and other existing routing schemes, especially at higher node speeds and data rates.

多波束FDD节点机载网络双向流量多路径本地路由修复方案


考虑由配备多波束天线的节点组成的定向机载网络。这些节点使用频分双工通信模式。这允许在一对源节点和目标节点之间形成多条路由，其中​​每条正向和反向路由完全重叠。这些路由中的每一个都支持双向流量。这些路由是使用双向自组织按需多路径距离向量 (BAOMDV) 路由协议形成的。在本文中，当这些路由由于节点移动性而中断时，我们提出了一种本地路由修复方案，称为 BAOMDV-LR。所提出的路由修复方案保留了路由的重叠和链路不相交（或节点不相交）特征，同时减少了昂贵的路由重新发现的需要。与 BAOMDV 和其他现有路由方案相比，所提出的方案显着提高了双向流量的整体网络性能（在数据包传递率、端到端延迟和路由开销方面），特别是在更高的节点速度和数据速率下。
