摘要: 针对边缘云增强光无线融合网络中节点能耗高的问题,提出一种协作休眠与调度的资源管理方案。在光域利用信令帧交互获取业务请求与云服务器缓冲区积压,采用负载水平感知的带宽分配方式制定保证业务共存的休眠时隙; 同时,联合带宽配置与无线节点能耗优化,在光域节点分配时隙的过程中调度无线域节点功率状态,降低网络能耗。仿真结果表明,所提出的方案能有效降低整个网络的能量消耗。

Abstract: In order to solve the problem of high energy consumption of nodes in the cloudlet enhanced fiber-wireless access network,a resource management scheme for cooperative hibernation and scheduling was proposed. This study used signaling frame interaction in the optical domain to obtain a service request and a cloud server buffer backlog,and adopted a load level-aware bandwidth allocation manner to formulate a sleep time slot for ensuring service coexistence. At the same time,combining with bandwidth configuration and wireless node energy optimiza-tion,the wireless domain node power state was scheduled during the allocation of time slots of the optical domain node,thereby reducing network energy consumption. The simulation results show that the proposed method can ef-fectively improve the energy efficiency of the whole network.
