This uptake is motivated, among other aspects, by the significant reduction in energy consumption that can be achieved by centralizing, consolidating and optimizing large IT infrastructures. At the same time, however, users expect to access cloud services via wireless access networks using smartphones and tablets. Several studies already show that wireless technologies such as WiFi and 4G are becoming the dominant access to cloud services. However, while energy efficiency is accounted for the end-user devices and data-centers, the actual energy consumption of wireless access networks is typically overlooked, even though it is expected to account for about 90 % of the entire wireless cloud energy footprint. In this paper, we use real-world measurements to present a complete analysis of the power consumption and performance of IEEE 802.11n. We also compare IEEE 802.11n with its predecessor, the widely deployed IEEE 802.11g standard, and confirm that 802.11n (2×2 MIMO) performs ~ 4.5 times better than 802.11g in terms of maximum network throughput as expected while at the same time reducing the required energy per bit by ~ 50%.","PeriodicalId":152857,"journal":{"name":"2013 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126614310","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}

In recent years, optimization of CDN data center energy consumption has attracted increasing research efforts. The key technical challenge is the tradeoff between CDN energy consumption and the content service capability at both the server and the network sides. In this article, we introduce a data center management scheme that effectively reduces the energy consumption of cross-domain CDNs through dynamically provisioning servers and coordinating content delivery operations with respect to dynamic server and network load. The proposed scheme focuses on optimizing the energy-performance tradeoff in two aspects. On one hand, servers in CDN data centers are put to the sleep mode during off-peak hours to save energy. On the other hand, CDN Quality-of-Service (QoS) performance is assured through honoring constraints on servers and network link loads, especially through restricting inter-domain content traffic volume. As a result, the proposed scheme is able to reduce CDN data center energy consumption without compromising its end-to-end QoS performance. According to our experiments based on realistic CDN scenarios, the proposed scheme is able to reduce data center energy consumption by up to 45.9% while achieving desired QoS performance.","PeriodicalId":152857,"journal":{"name":"2013 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132713022","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}

In this paper, we propose a fully distributed Demand Management System especially tailored to reduce the peak demand of a group of residential users. We model such system using a game theoretical approach; in particular, we propose a dynamic pricing strategy, where energy tariffs are function of the overall power demand of customers. In such scenario, multiple selfish users select the cheapest time slots (minimizing their daily bill) while satisfying their energy requests. We theoretically show that our game is potential, and propose a simple yet effective best response strategy that converges to a Pure Nash Equilibrium, thus proving the robustness of the power scheduling plan obtained without any central coordination of the operator. Numerical results, obtained using real energy consumption traces, show that the system-wide peak absorption achieved in a completely distributed fashion can be reduced up to 20%, thus decreasing the CAPEX necessary to meet the growing energy demand.","PeriodicalId":152857,"journal":{"name":"2013 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116677512","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}

Starting from this general framework and taking into account the novel green communication paradigm, the paper a cost-effective and energy-efficient localization architecture based on the improvement of classical cell-tower schemes coupled with a dynamic fingerprinting update phase in order to face the natural changes in the radio environments. The proposed system architecture has been implemented and tested in a real scenario to measure the performances in terms of accuracy and energy saving that will make it preferable to the traditional GPS-based systems in the next future. The obtained results show the effectiveness of the considered approach that makes possible to estimate the current position of a mobile user with a very small error (≈ 20m) also achieving an energy consumption reduction of about 38% respect to the classical GPS solutions.","PeriodicalId":152857,"journal":{"name":"2013 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133298157","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 potential to save energy at the base station (BS) by introducing delay in the downlink is constrained by both the non-ideal efficiency characteristics of power amplifier (PA) and the energy cost suffered by the mobile terminals (MT) due to the longer reception time. One possible way to control energy consumption at the MT is to introduce transmission delay in the uplink too. In this paper, we study the potential for energy saving by introducing transmission delay both in the uplink and in the downlink of a wireless network. We show that the energy saving potential depends on the network load (both uplink and downlink) and the PA efficiency (employed at the BS and the MT). Energy can be saved for most of the load combinations in uplink and downlink without draining out the battery of MT. One exception is the case with very low uplink load and very high downlink load. In that case, energy can be still saved at the cost of small excess energy consumption at the MT.","PeriodicalId":152857,"journal":{"name":"2013 IEEE Online Conference on Green Communications (OnlineGreenComm)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117082404","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}
