面向航空集群网络的改进型AODV路由协议

航空集群作战是未来空战重要作战模式,作战的场景、对象、态势更加复杂多变,经典的AODV(ad hoc on-demand distance vector routing)路由协议由于存在网络节点资源耗费不均以及无法适应网络拓扑结构快速变化等问题,不能很好地适应航空集群网络.提出一种基于资源可用模型和断裂链路快速修复模型的改进型AODV路由协议.协议通过设计资源可用模型改善航空集群网络中节点存储资源、计算资源、带宽资源耗费不均的问题,提高节点生存时间,并且通过设计断裂链路快速修复模型,降低重启路由发现频率,使其能更好地适应网络拓扑快速变化的航空集群网络.仿真表明,与经典的AODV协议相比,该协议在降低网络中死亡节点数目以及重启路由发现频率方面都有显著提升,对航空集群网络具有较强的适应能力.

Improved AODV routing protocol for aeronautic swarm network

Aeronautic swarm operation will become an important combat mode in the future, the scenes, objects and situation in swarm operation will become more complicated, the classical AODV routing protocol cannot meet the demand of rapid structural changes of network topology and the consumption of node resources are not well distributed. Therefore, an improved AODV routing protocol based on resource availability model and broken link quick repairing model (RaBlqr-AODV) is put forward in this paper. By designing resource availability model, this method can improve the storage resources, computing resources, bandwidth resources so that unbalanced consumption can be solved in aeronautic swarm network. Furthermore, the survival time of the node can be enhanced, and by means of designing broken link quickly repairing model and reducing the frequency of discovering restarted route, it can be better adapted to aeronautic swarm network. Simulation results show that the proposed protocol can significantly decrease the number of dead nodes in the network and the frequency of route discovery and has stronger adaptability to aeronautic swarm network compared with the classical AODV protocol.
