The primary transmitter is assumed to be an energy-harvesting node. We propose a three-stage cooperative transmission protocol. During the first stage, the primary user releases a portion of its time slot to the secondary nodes to send their data and to power the energy-harvesting primary transmitter from the secondary radio-frequency signals. During the second stage, the primary transmitter sends its data to its destination and to the secondary nodes. During the third stage, the secondary nodes amplify and forward the primary data. We propose five different schemes for secondary access and powering the primary transmitter. We derive closed-form expressions for the primary and secondary rates for all the proposed schemes. Two of the proposed schemes use distributed beamforming to power the primary transmitter. We design a sparsity-aware relay-selection scheme based on the compressive sensing principles. Our numerical results demonstrate the gains of our proposed schemes for both the primary and secondary systems.","PeriodicalId":315934,"journal":{"name":"2015 IEEE Globecom Workshops (GC Wkshps)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116824661","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 traffic includes calls within the VoIP network boundaries and others that are either initiated or terminated by other telephone networks, since most contemporary VoIP networks interconnect with other landline or cellular telephony networks. The traffic is originated by a multitude of user profiles. However on the calllevel basis, it can be described basically by two main processes, namely the Call Arrival and the Call Duration. Hence the aim of this work is the examination of the call arrival pattern and the extraction of a statistical distribution that can accurately describe this type of traffic. Also the call-duration times are analyzed to obtain the corresponding distribution. Hence, the contribution of the work is twofold. Firstly the data of a reallife VoIP network is examined for a long time-period which is independent from traffic patterns that occur within certain time periods or caused by events such as holidays and summer vacations. Secondly, the same data is differentiated based on the user behaviour in different time periods, such as working hours and weekends and the extracted results show differences between the statistical behaviour of the traffic. The presented results differ from other existing work and can be utilized to allocate resources more efficiently, to appropriately handle the network's traffic, to configure VoIP simulations in a more realistic way and to enhance the management of such networks.","PeriodicalId":315934,"journal":{"name":"2015 IEEE Globecom Workshops (GC Wkshps)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124725112","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}

Current network quality assurance processes, such as drive tests in wireless systems, typically focus on cell coverage and quality of service parameters (e.g., max. data rate) at a specific geographical position, without considering the impact of overload situations. Therefore, this paper introduces a methodology for stress testing a communication infrastructure for Smart Grids by synchronized, distributed so-called Smart Traffic Generators (STGs). Due to their low cost, the STGs become a permanent part of the infrastructure and enable a network operator independent, continuous network quality monitoring. A case study leveraging a LTE deployment demonstrates how the proposed approach can prove the fulfillment of Quality of Service (QoS) requirements of time critical Smart Grid applications, even in stress situations with high cell load. Although, the proposed approach has been introduced for Smart Grids, it can also be used for ensuring the communication resilience for other critical infrastructures, e.g., public safety networks.","PeriodicalId":315934,"journal":{"name":"2015 IEEE Globecom Workshops (GC Wkshps)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127374340","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}

Considering the rapid fluctuation of actual channel, we propose a multi-cell cooperation scheme named randomly selected cooperation with threshold (RSC-T), where the nearest BS in each tier is selected to transmit the user's data only when its instantaneous signal power received at a typical user is greater than a predetermined connecting threshold. Based on the proposed scheme, we derive integral expression for downlink coverage probability, and characterize it for a special case of two-tier HetNets. Comparison between RSC-T and traditional maximum- received-power (MRP) association scheme which always selects a BS with the strongest received signal power at the typical user is showed through numerical results and simulations. The numerical results indicate that (1) to get better performance than MRP, the connecting threshold should be below a critical point and the critical point increases with coverage SINR threshold. (2) there is always an optimal BSs density that provide the best coverage and the optimal density increases with connecting threshold.","PeriodicalId":315934,"journal":{"name":"2015 IEEE Globecom Workshops (GC Wkshps)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127487058","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}
