Since, the access networks are estimated to consume nearly 70% of the total Internet energy consumption worldwide, an effective strategy to reduce energy consumption must consider the deployment of energy-efficient solutions within the access network domain. In specific, this paper focuses on the energy-aware solutions within the hybrid optical wireless access network (HOWAN) environment. Currently, majority of the works in Green HOWAN are still limited to a specific functional layer. Nevertheless, we believe that it is also important to investigate a more comprehensive energy-efficient solution that includes more than just one functional layer. This paper proposes a framework for an integrated green solution that takes into consideration both the transmission and network layers. Low power modulation format such as OFDM is proposed over HOWAN that runs green routing algorithm. Preliminary results show transmission and network layer analyses of OFDM format and green routing algorithm over HOWAN. Future work aims at incorporating information of OFDM energy model over green HOWAN network layer analysis.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131083191","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}

OCDMA itself is attractive because of its beneficial features which includes asynchronous multiple access, robustness against interference, high security and flexible bandwidth assignment. In this paper, we present the simulative study and comparison of a multi dimension 2D-OCDMA network utilizing Enhanced Double Weight (EDW) code which has enhanced properties such as a cross-correlation value of 1 and has a simple encoder/decoder design.

Two types of Raman amplification systems are simulated; average power Raman amplifier model (APA-RFA) and bidirectional-fiber Raman amplifier model (Bi-Fiber RFA). A comparison is made between these two kinds of amplifiers under the same input power condition. As a result the saturation mechanism due to the large input signal is recognized in bidirectional fiber Raman amplifier model. This saturation is due to the stimulated Brillouin scattering that occurred once the input signal power exceeds the stimulated Brillouin scattering threshold (SBSTH). On the other hand, the average power Raman amplifier model exhibits constant Raman gain with the input signal power variation as the stimulated Brillouin scattering is not considered in this model. Finally, experimental results show significant agreement with the simulation results of the bidirectional fiber Raman amplifier model.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"193 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131873302","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}

The FFR principle is invoked for improving the cell-edge performance without reducing the throughput of the cell-center. Each cell is illuminated with the aid of six Remote Antennas (RAs), which are connected to the central base-station with the aid of realistically modelled imperfect optical-fiber links. When a Mobile Station (MS) is located at the cell-edge, the two nearest RAs can be invoked to detect and forward the user's signal to the base-station, based on the Single-Input Multiple-Output (SIMO) principle. Furthermore, we design a Turbo Coded (TC) 16-level Star-Quadrature Amplitude Modulation (StQAM) scheme for supporting optical-fiber-aided cooperative wireless transmission, where the receiver does not have to estimate the channel state information. Hence, a lower detection complexity can be achieved when compared to coherently detected schemes, albeit naturally, at a 3 dB power-loss. We also investigated the effect of phase-rotation imposed by imperfect optical-fiber links. We found that our noncoherent TC-StQAM scheme is robust to both wireless and optical-fiber imperfections.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121815409","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}
