针对卫星移动性以及地面网络资源受限问题,首先提出一种基于命名数据网络的地面网络内容预先放置策略;然后,充分考虑多个基站覆盖范围下内容局部请求分布的差异性,提出一种基于公平的卫星网络内容分发策略。仿真实验结果表明,在卫星网络内容注入方面,所提内容预先放置策略是有效的;在卫星网络内容分发方面,所提出的基于公平的内容分发策略可以实现最大化内容满意度。
In view of the problem of satellite mobility and terrestrial network resource constraints
a pre-placement strategy for terrestrial network content based on named data networking was proposed; Then
local content requests under the coverage of multiple base stations was fully considered.Based on the diff erence in distribution
a content distribution strategy based on fairness in satellite networks was proposed.The numerical results showed that the proposed content pre-placement strategy was eff ective in terms of satellite network content injection.In addition
in terms of satellite network content distribution
the proposed fair-based content distribution strategy could maximized content satisfaction.
