摘要
对卫星网络路由算法研究中存在的问题进行了分析。建立了卫星网络的多约束数学模型,该模型表示了多约束条件下的最小代价问题。在数学模型研究的基础上,对多约束路由算法进行研究,得到一种多约束切换最优路由算法。该算法能够有效地降低路径的切换概率,能够提高计算效率,通过分析表明该算法具有较好的性能。
The problems of routing algorithms in satellite network are analyzed. The multi-constrained mathematical model of satellite networks is built, which shows the multi-constrained optimal problem. Based on the mathematical model, the multi-constrained route algorithm is studied, and a new optimal algorithm is pro- posed. The new algorithm can reduce handover probability and enhance the computational efficiency. Simulation results show that the algorithm has better performance.
