摘要

摘要: 針對跨域節(jié)點間的協(xié)同休眠、休眠節(jié)點負載轉(zhuǎn)移時導(dǎo)致的網(wǎng)絡(luò)擁塞等問題，該文提出一種帶有負載轉(zhuǎn)移的跨域節(jié)點協(xié)同休眠機制。通過分析光網(wǎng)絡(luò)單元(ONU)當(dāng)前負載及休眠ONU與無線路由器間相關(guān)性選擇休眠節(jié)點，并結(jié)合最大匹配理論確定休眠節(jié)點轉(zhuǎn)移負載的目標(biāo)節(jié)點，從而在保證網(wǎng)絡(luò)連通性及業(yè)務(wù)低時延的基礎(chǔ)上，進一步降低網(wǎng)絡(luò)能耗。仿真結(jié)果表明，所提出的算法在有效降低整網(wǎng)能耗的同時不會對網(wǎng)絡(luò)數(shù)據(jù)包時延產(chǎn)生顯著影響。

Abstract: 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.
