摘要

本文将系统级诊断引入到卫星网络的故障诊断领域.针对卫星可以具有多个通信方向且可以部分通信失效的特性

提出了一种新颖的卫星网络建模方法——双层节点图

设计了基于广播的卫星网络系统级诊断方案

并对其通信开销进行了理论分析.测试中充分利用了卫星广播和一对多的通信模式

使本方案不但适用于任意类型的网络拓扑

而且可以节省通信量.仿真结果表明诊断的通信开销随网络中可通信端口数量的减少而下降.

Abstract

System-level diagnosis was introduced into the fault diagnosis for satellite networks.A novel modeling method for satellite networks

two-level-node graph

was presented to characterize the specialty that a satellite could have more than one communication directions and its communication function could be faulty partly.Then a strategy of the system-level fault diagnosis for satellite networks was designed based on broadcast and its communication complexity was analyzed theoretically.The satellites' broadcast and one to many communication modes were taken advantage of when testing so that our strategy is applicable to arbitrary topology and saves communication overhead.Simulation results show that the communication overhead reduces while the number of ports

which can communicate

decreases.
