非完全合作网络环境下的信息高效分发理论与关键技术

With the rapid development of aviation industry, the flight number is continuously increasing, the scope of operation is being further expanded, the cooperation and competition among aircrafts are more frequent, and the limited airspace becomes a typical incomplete cooperative network environment, which causes that the traditional information dissemination theory cannot be directly applied. Based on the actual secure flight requirements of aircrafts in incomplete cooperative aviation network, this project explores and studies the information on efficient and reliable dissemination theory and critical techniques with the core of Network coding: first it establishes a complex limited airspace space time network topologic model, studies the optimal stopping time theory bound of algebraic gossip mechanism, proposes network coding algorithms targeting at actual application; in different price mechanism circumstances, in areas of transmission strategy (network coding or routing) and user amount, it studies the theory bound of node selfish behavior impact on the network performance, designs network coding, routing and resources distribution coordinated gaming algorithms. Through the study and research of this project, it proposes new thought, new theory, and new techniques on information efficient dissemination in incomplete cooperative network environment, which provides theory foundation and technique basis to multiple intensive flight and has a theoretical significance and practice value to reasonably make use of limited airspace resources.

随着航空业的快速发展，飞行量持续增加，运行范围的进一步扩大，飞行器之间的合作竞争日趋频繁，受限空域成为一个典型的非完全合作网络环境，导致传统的信息分发理论无法直接应用。本项目针对非完全合作航空网络中飞行器安全飞行的实际需求，探索和研究以网络编码为核心的信息高效可靠分发理论与关键技术：首先建立复杂受限空域时空网络拓扑模型，研究代数闲聊机制的最优停止时间理论界问题，提出面向实际应用的网络编码算法；在不同价格机制条件下，从传输策略(网络编码或路由)和用户数目两方面，研究节点自私行为对网络性能影响的理论界问题，设计网络编码、路由和资源调度分配联合博弈算法。通过本项目的研究，提出非完全合作网络环境下信息高效分发的新思路、理论方法和技术，为实现多重密集飞行的精准引导提供理论支撑和技术基础，对提高航空飞行安全，合理利用有限空域资源具有重要的理论意义和实用价值。
