【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。
[Abstract]:Aiming at the reliability guarantee problem of communication between nodes in future aviation cluster networks, a route selection strategy for link reliability estimation based on mobile prediction is proposed. Firstly, the location of neighbor nodes is accurately predicted by using geographical location based mobile prediction method. Secondly, according to the prediction results, the communication range of the current node is partitioned, and the link reliability of different neighbor nodes is estimated respectively to obtain the corresponding reliability estimation function. The probabilistic selection model is used according to the reliability function value and the hop factor is used to select the route. Finally, based on the optimized Link State routing protocol OLSR, the details of the routing strategy are described, and the effectiveness of the proposed routing strategy is verified by simulation. The experimental results show that the proposed strategy can effectively improve the reliability of communication between nodes on the basis of being suitable for the aviation cluster network.
