论文摘要
在本文中，为室内可见光通信（VLC）系统中的回程连通性提出了节能的被动光网（PON）体系结构。所提出的网络用于支持雾计算体系结构，允许具有处理需求的用户访问建筑物内其他用户设备中的专用雾气节点和空闲处理资源。建筑物内的雾资资源补充了访问和地铁网络和中央云数据中心的较高层的雾气节点。开发了混合整数线性编程（MILP）模型，以最大程度地减少与所提出的体系结构相关的总功耗。结果表明，与基于最先进的脊柱和叶片连接性的体系结构相比，pon backhaul网络将雾计算的能源效率提高了66％，处理12％。
In this paper, an energy efficient passive optical network (PON) architecture is proposed for backhaul connectivity in indoor visible light communication (VLC) systems. The proposed network is used to support a fog computing architecture allowing users with processing demands to access dedicated fog nodes and idle processing resources in other user devices within a building. The fog resources within a building complement fog nodes at higher layers of the access and metro networks and the central cloud data center. A mixed integer linear programming (MILP) model is developed to minimize the total power consumption associated with serving demands over the proposed architecture. The results show that the PON backhaul network improves the energy efficiency of fog computing by 66% for networking and 12% for processing compared to an architecture based on state-of-the-art Spine-and-Leaf connectivity.
