GE信道下WLAN节能站点传输TCP流功耗分析模型

摘要

针对目前在无线局域网(WLAN)基础服务集(BSS)节能站点功耗分析模型上没有融入错误信道模型的问题,有机地结合了Gilbert-Elliot(GE)错误信道模型和WLAN BSS节能模式站点传输TCP流的功耗模型,提出并建立一种新的混合模型,同时给出了GE信道参数影响节能站点传输TCP流功耗的量化表达式,通过网络模拟器(NS2)仿真验证了新模型的正确性和有效性.%Nowadays,there had been a problem that error channel models were not considered into energy consumption model of WLAN BSS power saving stations. With combination of GE error channel model and energy consumption model for transmission of TCP flows on power saving stations (STAs) in WLAN BSS, this paper suggested a new hybrid model. Then, provided quantized expression to figure out how GE channel parameters affected energy consumption in transmission of TCP flows on power saving STAs, and verified validity of this new model by simulating with NS2.
