摘要

针对卫星网络链路时延长和拓扑时变的特点

给出一种可满足时延限制且在业务持续时间内尽可能不发生中断的时延受限最优寻路(SDCOP)算法

该算法通过预测拓扑链接情况来有效降低链路切换对网络QoS的影响

且具有计算复杂度低

可适应星上设备处理能力的要求等优点。仿真表明算法在计算复杂性、业务阻塞率以及业务中断率方面都优于同类算法。

Abstract

By the analysis of the characteristics of mobile satellite network

such as a long delay and a topological time-varying

a novel satellite network delay constraint optimal path（SDCOP）algorithm

which could obtain a path to sat-isfy the delay constraint condition as well as the minimization of interruption during the service

was proposed.This algo-rithm exploits the predictive nature of connectivity changes of time-varying topological to decrease the influence in the QoS routing performance caused by the handover.Besides

it has a low computing complexity to adapt to the restricted computing capability of satellite equipments.Correlative simulation indicates that this novel algorithm is superior to other current algo-rithm in respect of computing complexity

service blocking probability and interrupting probability etc.
