对飞机编队内部和飞机编队之间的紫外光通信网络工作模式以及相应的MAC层协议进行研究。为保证编队内所有飞机的信息共享与交互,编队内部采用非直视通信NLOS(a)模式;为保证通信距离和质量,编队之间采用NLOS(c)模式进行通信。机间紫外通信组网MAC层协议以原IEEE802.11DCF协议为基础,对传统二进制指数退避算法进行改进,提出了一种基于分段思想的动态退避算法并进行了仿真研究,仿真结果表明:该算法与传统算法相比具有时延短,吞吐量大的特征,更适用于机间紫外通信网络。
The working mode of the ultraviolet communication network between the aircraft formation and the aircraft formation and the corresponding MAC layer protocol are studied. In order to ensure the information sharing and interaction of all the aircraft in the formation, NLOS (a) mode of non-direct-view communication is adopted in the formations. In order to ensure the communication distance and quality, the formations use NLOS (c) mode to communicate. Based on the original IEEE802.11DCF protocol, the MAC layer protocol of inter-machine UV communication network is improved on the traditional binary exponential backoff algorithm. A dynamic backoff algorithm based on the segmentation idea is proposed and simulated. The simulation results show that Compared with the traditional algorithm, the algorithm has the characteristics of short time delay and large throughput, and is more suitable for the inter-machine UV communication network.
