{"title":"Systematic analysis of geo-location and spectrum sensing as access methods to TV white space","authors":"H. Mauwa, A. Bagula, M. Zennaro, E. Pietrosemoli, A. Lysko, T. Brown","doi":"10.1109/ITU-WT.2016.7805706","DOIUrl":"https://doi.org/10.1109/ITU-WT.2016.7805706","url":null,"abstract":"Access to the television white space by white space devices comes with a major technical challenge: white space devices can potentially interfere with existing television signals. Two methods have been suggested in the literature to help white space devices identify unused channels in the TV frequency band so that they can avoid causing harmful interference to primary services legally protected to run on the band. These methods are geo-location spectrum database and spectrum sensing. Discussions in the literature have placed much emphasis on the limitations of the spectrum sensing approach and mainly based on the developed world environment ignoring the performance requirements of the geo-location database approach and how the absence of these requirements in a developing region could affect its performance. This paper considers a broader analysis of the approaches by looking at factors that can affect the performance of each approach and how the presence or absence of these factors in a developed region or developing region can affect their performance. In so doing, the paper highlights the need to conduct more research on the performance of spectrum sensing in developing regions where there are plenty of white spaces to ascertain its use in these regions.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126346439","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}

{"title":"A community-driven information system to develop next generation collaborative and responsive rural community (NCoRe)","authors":"J. Basak, R. Parthiban, Siuli Roy, S. Bandyopadhyay","doi":"10.1109/ITU-WT.2016.7805727","DOIUrl":"https://doi.org/10.1109/ITU-WT.2016.7805727","url":null,"abstract":"Much of the ICT interventions for rural transformation are exogenous in nature (development from outside), in the sense that they use a \"push\" approach towards development, without considering the nature and problems of an individual member of the rural community. Information and knowledge transactions, especially with dis-empowered people and groups, are a complex process and ICT needs to be appropriated and used in a way that helps resolve daily concerns. With this perspective in mind, this paper proposes NCoRe, an interactive community-driven information system platform to harness the potential of community participation in governance. In a digitally-connected global society, each individual in a community of people is not only a consumer of information but also a producer of information: a potential contributor in many ways to build a better community. NCoRe exploits the potential of community knowledge, making them available to the community and empowering the communities to interact, collaborate and participate in the development of society and transforming the way they live, learn and work. NCoRe is an ongoing initiative to build next-generation collaborative and responsive community by empowering the rural community of India with an ICT-enabled \"capability framework\" involving the self-help groups (SHG): the micro-communities within a village community.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124149303","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}

For discovery, remote access and management of these IoT devices, an IoT directory service is needed to store and provide their various attributes such as location, generated data types, owner's name, and security keys. In this paper, we present the architectural design of the IoT directory service that is capable to store a huge number of heterogeneous records and provide fast lookup (latency of few milliseconds) and dynamic update (latency of few seconds), while fully complying with owner- or user-centric security and privacy policy. To meet the performance requirements despite fluctuations in the workload and networking environment, we leverage tools of network function and resource virtualization to dynamically allocate and adjust the computational and network resources assigned to the directory service.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116056908","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}

When PAPR is high, the end-user power amplifier's dynamic range should also be high, resulting in costly power amplifiers. Single-carrier frequency-division-multiple-access (SC-FDMA) is used as the air-interface in LTE-Advanced, and this paper proposes a novel and efficient technique for PAPR reduction via pulse shaping for interleaved-FDMA (IFDMA) subcarrier mapping in SC-FDMA. By way of simulations, we show that PAPR can be reduced by 2.11 dB for our novel pulse shaping compared to raised cosine (RC) pulse shaping with QPSK modulation.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126445561","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 design and develop middle-box splitting functionalities for chunked video exchanges (i.e., file transfer and streaming) over multiple concurrent paths over South Korea, Malaysia, and Thailand parts of OF@TEIN SDN-Cloud playground. To reduce middle-box processing delay and to enable multi-path capacity leverage, we propose to combine the multi-path file-transfer function and Tsunami protocol. This combination allows the multi-path-based pre-fetch transfer of 4K-video chunks from Tsunami server in South Korea to Thailand's SmartXBox. The experiment results show that the proposed scheme can reduce 23~72 seconds in transferring 10-minute 4K-video file by effectively utilizing the available international multi-path capacity.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124025719","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}

To better manage the Internet usage move from host-centric communication to receiver-driven content retrieval, revolutionary ICN architectures have been proposed. A distinguished characteristic of these innovative architectures is to provide ubiquitous and transparent in-network caching to enhance network resource utilization and accelerate content dissemination. With the exponential increase of Internet traffic, the issue of content storage is a growing concern in ICN. In this paper, we present a caching strategy that considerably increases cache hit rate and reduces stretch ratio, which are the most important metrics in the evaluation of ICN caching. Through extensive simulations, it is shown that our proposed work is a favorable and realistic contribution for the standardization exercise of data caching for achieving accurate and valid network performance in the future Internet.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116732270","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}
