中文摘要：
针对跨域节点间的协同休眠、休眠节点负载转移时导致的网络拥塞等问题,该文提出一种带有负载转移的跨域节点协同休眠机制。通过分析光网络单元（ONU）当前负载及休眠ONU与无线路由器间相关性选择休眠节点,并结合最大匹配理论确定休眠节点转移负载的目标节点,从而在保证网络连通性及业务低时延的基础上,进一步降低网络能耗。仿真结果表明,所提出的算法在有效降低整网能耗的同时不会对网络数据包时延产生显著影响。
英文摘要：
For the problem of cross-domain node sleep and network congestion caused by load transfer, this paper propose an energy-efficient policy based on collaborative sleep mechanism between cross-domain node with load transfer in WOBAN. By analyzing the current load of the Optical Network Unit （ONU） and the collaboration between ONU and wireless router, this paper applies maximum matching theory to determine sleep node and the destination of load transfer so as to reduce energy consumption on the basis of ensuring the connectivity and low latency of network. Simulation results show that the proposed algorithm can reduce the energy consumption of entire network without having a significant impact on the network packet delay.
