在NDN的设备到设备通信中基于势能的路由策略

发布时间：2021-11-26 00:48

　　设备到设备（D2D）通信作为一种重要的新技术,对未来网络技术如5G和物联网（IoT）有着重要的推动作用。其泛在通信的特点可以有效解决流量爆炸问题,并有望实现超低时延通信。尽管有上述优势,在具体的网络应用场景中,传统的D2D在缓存和转发策略方面仍然存在着有效性与可靠性的问题。因此,本文提出基于命名数据网络（NDN）的D2D架构。在此基础之上,本文提出了基于势能的路由（PBR）策略。路由势能由内容的质量以及节点之间的接近程度来定义。PBR根据每个节点的路由势能做出路由决策,进而找到从用户到可用内容副本之间的最佳路径。仿真结果表明,与传统的解决方案相比,该方案可以明显提升平均响应延迟和缓存命中率方面的性能。
