In this paradigm, there is a need to optimally allocate resources with a view to maximizing the utility, e.g., the total throughput, and mitigating the interference caused by sharing the same spectrum between cellular users (CUs) and D2D pairs. This paper proposes a scheme for optimally allocating transmit power levels and channels to maximize the total number of active D2D pairs and reused channels while minimizing the aggregate transmit power pertaining to CUs and D2D pairs. We consider a multi-cell scenario in which the transmitter and the receiver of each D2D pair can be in the same cell or in two different cells, and each user can simultaneously transmit over multiple reused channels. The optimization is done via a centralized baseband processing in the cloud radio access network (C-RAN) architecture. Simulations show that via our proposed scheme, more users (both cellular users and D2D pairs) can simultaneously communicate and the total system throughput is also significantly increased.","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":"115106649","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}

There are plenty of tools available for experimenters ranging from simulation tools, emulation equipment, to small and large scale experimentation testbeds. Each of these performance evaluation frameworks introduces a series of capabilities and drawbacks. Additionally, there is a need for using a common methodology to perform different performance tests and to create comparable outcomes. Seeking for the standardization of reliable and comparable Internet speed measurements and trying to provide end-users with trustworthy measurement tools, different SDOs have standardized different measurement methodologies. This paper focuses on the applicability of the distinct measurement frameworks and methodologies in the field of mobile Internet, with special focus on the impact of using TCP over mobile broadband connections. The paper describes a series of experiments over different frameworks and, based on the obtained results, identifies the implications of the different types of performance tests into the evaluation outcomes and states the need for large scale measurements.","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":"116618550","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}

There is a pressing need then to ease developers and service providers in embracing the opportunity, and that means offering a platform for such efforts. This in turn means providing a solid foundational architecture with abstractions and sound layering for MCS application designs to be mapped over it. This should base on a flexible infrastructure able to provide resources to MCS applications according to their requirements, hopefully on-demand. A service-oriented/Cloud model can perfectly fill this gap. This paper is a first step in this direction, proposing to adopt Stack4Things (S4T), an OpenStack-based platform for managing sensing and IoT nodes, for runtime customization of resources and their functions to support MCS services and applications. This implies developing and extending the S4T platform further to the specific requirements coming from off-the-shelf, e.g., Android-based, mobiles, as well as describing an example S4T-powered MCS application, Pothole Detection Mapping, to highlight the role of the platform.","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":"122091688","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 underlying cloud-based Internet-of-Things (IoT-Cloud) infrastructure is aimed to be implemented in the city of Lubumbashi in the republic Democratic Republic of the Congo (DRC) with the objective of setting up a community health care network around a mesh of health kiosks. We propose a deployment model for the proposed Cyber-healthcare system, and describe a patient prioritization process as part of its situation awareness component. The results obtained from an experimental prototype reveal the field readiness of the off-the-shelf bio-sensor technology used by the system, the performance achieved when using a solar powered subsystem, the relative communication capabilities provided by its protocols and the network engineering feasibility of the planned community health care network. The relative efficiency of using supervised machine learning compared to unsupervised machine learning when performing patient prioritization, is also revealed through two popular algorithms: Multivariate linear regression (MLR) and K-means clustering (KMC).","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":"120855105","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}
