【摘要】：針對全球微波互聯(lián)接入(Wi MAX)網(wǎng)絡(luò)節(jié)能算法中因移動節(jié)點(diǎn)(MS)的信道質(zhì)量差別引起的空閑狀態(tài)而浪費(fèi)能量這一不足,依據(jù)IEEE 802.16e標(biāo)準(zhǔn)第Ⅰ類節(jié)能模型給出了MS服務(wù)質(zhì)量目標(biāo)的平均能耗(AEC)形式化描述,并提出一種基于信道質(zhì)量均衡的避免終端空閑狀態(tài)虛擬突發(fā)的節(jié)能調(diào)度(IAVB)算法。該算法采用將空閑狀態(tài)閾值和基于信道質(zhì)量的狀況選擇主移動終端相結(jié)合的策略,并完善了虛擬突發(fā)的結(jié)束條件,很好地避免了因未正確結(jié)束虛擬突發(fā)而導(dǎo)致的終端空閑狀態(tài)造成的能量浪費(fèi)問題。仿真實(shí)驗(yàn)表明,在節(jié)能方面IAVB算法比最長虛擬突發(fā)優(yōu)先(LVBF)算法性能平均提高了15%。實(shí)驗(yàn)結(jié)果表明該算法減少了終端的空閑狀態(tài),有效地降低了終端能耗,提高了Wi MAX網(wǎng)絡(luò)的資源利用率。
[Abstract]:In the energy saving algorithm of Wi MAX (Global Microwave Interconnect access) network, the idle state caused by the difference of channel quality between mobile nodes MSX is not enough to waste energy. Based on the energy saving model of class I of IEEE 802.16e standard, this paper presents the formal description of the average energy consumption of MS quality of service target, and proposes an energy saving scheduling algorithm based on channel quality equalization to avoid virtual burst of idle state of terminal. The algorithm combines the idle state threshold with the channel quality-based condition to select the main mobile terminal, and improves the termination condition of the virtual burst. The problem of energy waste caused by terminal idle state caused by incorrect termination of virtual burst is well avoided. The simulation results show that the performance of the IAVB algorithm is improved by an average of 15% compared with the longest virtual burst priority algorithm in the aspect of energy saving. The experimental results show that the algorithm can reduce the idle state of the terminal, reduce the terminal energy consumption, and improve the resource utilization of the Wi MAX network.
