固定航线的航空自组网连通性研究

网络连通性是组网与路由研究的前提和基础,针对目前对固定航线航空自组网连通性研究较少的现状,提出一种连通性研究方法.该方法结合实际航线分层、双向的特点,通过建立飞机分布模型与航线模型,推导出了一维航线连通性表达式.在此基础上,运用基于概率矩阵的概率图求解方法对航线网的连通性进行理论研究,并用实验证明其正确性.随后,根据实际航班数据对我国部分空域内一维航线及航线网的连通性进行仿真,结果表明航空自组网在上述空域具备可行性.最后,从航班安排、航线规划等4个方面对提升连通性给出了合理性建议.

Connectivity on fixed air route in aeronautical ad hoc networks

Connectivity is the premise and foundation of networking and routing. Researches on fixed air route connectivity in aeronautical ad hoc networks are inadequate at present. Aiming at this situation, a method of connectivity researching was introduced. By combining characteristics of realistic layered with two-way air routes, and building the aircraft distribution as well as flight route models, the method deduced a math expression of one-dimensional route connectivity. Based on the above, probability figure was used to study on the network connectivity in view of probability matrix, and the correctness of the results were proved by experiments. Then, according to the practical flight data, the connectivity of one-dimensional route and network in Chinese partial airspaces was simulated; indicating that aeronautical ad hoc networks in the mentioned airspaces are feasible. Finally, some reasonable advises are given to improve the connectivity in four aspects, such as flight arrangement, planning and so on.
