针对航空高动态网络(HDAN,Highly Dynamic Airborne Networks)节点高速运动、拓扑结构变化频繁、飞行器轨迹时变等特性,及其所带来的数据到达率低、信息拥塞度高、稳定性差等问题,提出一种具有负载感知特性的路由算法.算法提出了新的动态路由因子度量来适应拓扑结构的变化,引入节点相对速度修正高动态环境下单纯地理位置信息所带来的误差,并通过交互邻居节点队列信息表征网络局部负载程度,降低拥塞概率.仿真实验结果表明,本算法有效减少了网络丢包率和通信时延,增强了信息传输的可靠性.
In order to solve the problems such as the high-speed motion of nodes in Highly Dynamic Dynamic Airborne Networks (HDANs), the frequent changes in the topology structure, time-varying trajectory of aircraft and the low data arrival rate, high congestion and poor stability of nodes, This paper proposes a new routing algorithm with load-sensing characteristics. The algorithm proposes a new dynamic routing factor metric to adapt to the change of topology, introduces the relative speed of nodes to correct the error caused by mere geographical location information under high dynamic environment, Node queue information characterizes the local network load and reduces the probability of congestion.The simulation results show that the proposed algorithm can effectively reduce the network packet loss rate and communication delay and enhance the reliability of information transmission.
