Abstract: To solve the problem of inter node communication reliability guarantee in future aviation cluster networks, a mobile prediction based link reliability estimation routing strategy is proposed. First of all, preciously predicting has been done for neighbor node location by using the mobile location prediction method. Secondly, according to the predicting results, the communication range of the current node is partitioned, the link reliability of different neighbor node area are estimated by the reliable estimation of the corresponding function value. According to the obtained reliability function values, the probabilistic selection model is adopted and the hop factor is combined to route selection. Finally, the OLSR protocol is used as the carrier to describe the routing policy details. Simulation results show the effectiveness of the routing strategy proposed in this paper. The experimental results show that the proposed method can effectively improve the reliability of communication between nodes in the application of aviation cluster network.

摘要： 针对未来航空集群网络中节点间通信可靠性保障问题，提出一种基于移动预测的链路可靠性估计路由选择策略。首先，使用基于地理位置的移动预测方法对邻居节点的位置进行准确预测。其次，根据预测结果对当前节点的通信范围进行分区，对不同邻居节点所在区域的链路可靠性分别估计得到相应的可靠性估计函数值。根据得到的可靠性函数值使用概率选择模型并结合跳数因子进行路由选择。最后，以优化链路状态路由协议（Optimized Link State Routing protocol，OLSR）为基础对路由选择策略细节进行描述，并仿真验证了提出的路由选择策略的有效性。实验结果表明，该策略在适用于航空集群网络的基础上，能有效提高网络中节点间通信的可靠性。
