摘要:

近年来,临近空间组网成为研究热点,然而临近空间飞行器运行轨迹复杂和高动态的特性为实现可靠通信增加了难度,必须使用合适的移动模型对其性能进行仿真分析。分析了临近空间飞行器完整的运行轨迹,利用QualNet平台建立了飞行中各个阶段的模型,并基于无线自组网按需平面距离向量(AODV)路由协议进行了性能仿真,仿真结果为今后设计空天地-体化飞行器测控通信网提供了一定的依据。

Abstract:

In recent years, near space network has become a research hotspot. However, it is difficult to achieve reliable communication due to the complex path and high dynamic characteristics of near space vehicle, and thus it is necessary to simulate the performance based on proper mobility model. This paper analyzes the whole path of the near space vehicle, sets up models at different flight phases on QualNet platform, and conducts performance simulation based on ad hoc on-demand distance vector(AODV) routing protocol.Simulation results provide some bases for the integrated-space-air-ground spacecraft TT&C(telemetry, tracking and command) and communication network.

Key words: near space, path, network, QualNet, simulation
