But the well known performance anomaly of 802.11 still remains an open issue. A mobile station tends to change its modulation and coding scheme and transmit at lower bit rate due to the signal fading and interference. Besides, the 802.11 commercial devices adopt a simple First-In-First-Out (FIFO) scheduler without isolating the traffic flows addressed to different destinations. These have lead to a problem: whenever one or more stations transmit at lower bit rate, the performance of all the stations is heavily degraded. Our experimental results have pinpointed this problem. To counteract this problem, we propose an easy to deploy and portable solution to be implemented in the 802.11n base station, known as anomaly-aware IP scheduler with admission control. This cross-layer approach requires no modification to the current 802.11 standard and runs on top of the Linux kernel. The experimental results have shown the feasibility of our solution in minimizing the performance anomaly problem.","PeriodicalId":433243,"journal":{"name":"2008 International Symposium on High Capacity Optical Networks and Enabling Technologies","volume":"428 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133451671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This system is characterized by having both a fiber optic link and free-space radio path to exploit the synergy of two complementary technologies; the broadband mobile wireless access and fixed optical access. Optoelectronic mixing is required in RoF systems to detect the RF modulated optical signal and perform frequency up-conversion. In this work, three-terminal InP/InGaAs HBT with optical access has been used as the optoelectronic mixer (OEM) for front-end RoF optical receiver configuration. Thus in this configuration, the photodetection and frequency conversion can be achieved in p-i-n photodiode and HBT device, which considerably simplify the conventional method. The RoF OEM was successfully simulated using a nonlinear microwave simulator to perform harmonics balance analysis, which represented actual photodetection model and nonlinear dynamic optoelectronic mixing behavior. In this paper we reported the - 5.2 dB maximum internal mixing efficiency for 400 MHz IF modulated signal to 3.4 GHz upconverted RF signal with LO power is -2dBm, and that agreed with conventional theoretical analysis. In this article, the theory of operation, the device structure of the RoF OEM and its characteristic will be presented.","PeriodicalId":433243,"journal":{"name":"2008 International Symposium on High Capacity Optical Networks and Enabling Technologies","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114657064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
