航空集群机载网络Failure-Oblivious路由策略

航空集群机载网络作为集群成员间信息交互的纽带,其路由策略性能优劣直接影响信息传输实时性与可靠性,从而制约网络化集群作战效能发挥。考虑到航空集群机载网络具有诸多不确定性,为应对路由失效以及尽可能避免路由更新,从路由选择算法的角度,在软件定义网络架构下提出Failure-Oblivious路由策略。与传统路由策略不同的是,该策略利用随机算法生成多条路由,能够在不进行路由失效预测的情况下应对路由随机失效问题。理论推导与仿真验证表明,该策略能够在保证通信时效性代价可控的基础上,降低航空集群机载网络路由失效风险。

Failure-Oblivious routing strategy in airborne network for aeronautic swarm

Airborne network for aeronautic swarm is the information interaction bond between swarm members, whose routing strategy directly affects the real-time performance and reliability of information transmission, and then affects the combat effectiveness of networked swarm. Considering that there are many uncertainties in airborne network for aeronautic swarm, in response to the risk of route failure and avoid routing updates, a Failure-Oblivious routing method from the perspective of routing algorithm was proposed under software-defined network architecture. Unlike traditional routing strategies, this method can deal with routing failure problem without the burden of predicting routing failure by using random multipath routing algorithms. Theoretical derivation and simulation verification show that this routing method can reduce the risk of route failure in airborne network for aeronautic swarm, thus guaranteeing that communication delay cost is under control.
