However, existing studies have not paid enough attention to the influence of negotiation power of the involved parties. In this paper, two incentive mechanisms for cooperative relaying are proposed, wherein the source possesses different degrees of negotiation power. One mechanism is for the source with strong negotiation power posting a series of take-it-or- leave-it contract offers for the relays while the relays are not entitled to negotiate the counteroffers, and the other mechanism is for the source with weak negotiation power while the relays confer substantial negotiation power, i.e., are capable of doing business with the source by crafting more profitable deals. The relay selection rules, the optimal amounts of relaying service, and the optimal rewards for the relays, are derived for the proposed mechanisms, respectively. A distributed algorithm is further proposed to iteratively obtain the optimal solution for the second mechanism. A case study is also presented to show the influence of negotiation power on the behaviors of the participants and the efficiency and distribution of profits. Numerical results are provided to verify the theoretical analyses of the proposed mechanisms.","PeriodicalId":201848,"journal":{"name":"2018 IEEE Global Communications Conference (GLOBECOM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134480798","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}

Conventionally, VLC waveforms are designed to target specific services. In services that require high-speed access, multi-carrier modulation techniques, i.e., orthogonal frequency division multiplexing (OFDM), is considered. For lower-speed access services, single carrier modulation techniques are considered such as phase-shift keying (PSK) or pulse-position modulation (PPM). The proposed design offers a universal-and receiver-independent multi-tier waveform that is expected to serve the requirements of fifth-generation (SG) wireless networks and beyond, including high-speed connectivity, sensing and positioning services. This allows a wide variety of devices to extract a useful portion of the received waveform associated to the targeted service while ensuring inter-service-interference-free operation. In addition, the proposed design aims for cooperative transmission and dimming control to enhance the lighting environment for better user experience. The paper provides a detailed description of the design process and the experimental evaluation. The experimental results indicate that the designed waveform can offer dimming control over 60% of the light-emitting diode (LED) full dynamic range, while maintaining bit-error rate (BER) of $7times 1{0}^{-5}$ for 64-quadrature amplitude modulation (64-QAM).","PeriodicalId":201848,"journal":{"name":"2018 IEEE Global Communications Conference (GLOBECOM)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127419664","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}

Conventional systems based on electromagnetic induction or X- rays are effective, but have small coverage areas in addition to requiring costly infrastructure. In this paper, we explore the use of ubiquitously present WiFi signals for non-obtrusive detection of concealed metal objects. For the purpose, we build a prototype system consisting of a single- antenna commodity WiFi radio as a transmitter, and two multi-antenna radios as receivers placed in an indoor environment of approximately 42 ft by 39 ft. We conduct extensive experiments with subjects walking through the setup with (or without) a sheet of metal placed around their chests. We use the channel state-information collected from the receivers to train a deep convolutional neural network, and find that the proposed system can differentiate between the metal and non-metal cases with an average accuracy of 86.44.","PeriodicalId":201848,"journal":{"name":"2018 IEEE Global Communications Conference (GLOBECOM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133854300","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}

Traditional beam training methods are inaccurate and time-wasting, leading to unstable and inefficient wireless networks. Therefore, in this paper, we attempt to address this problem from a new aspect, i.e., assisting the signal adaptation with human mobility prediction. A state-of-the-art long short-term memory (LSTM) model is adopted to analyze the past trajectories and predict the future position, which can serve as an important reference for the transmitters to proactively adjust their beams and provide seamless coverage. In addition, we also design an algorithm to optimize the beam selection problem and improve the network quality. To the best of our knowledge, this is the first work in the field to use deep learning models for the beam selection problem. Simulations demonstrate that our approach is robust and efficient, and outperforms the state-of-the-art in several related tasks.","PeriodicalId":201848,"journal":{"name":"2018 IEEE Global Communications Conference (GLOBECOM)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115335345","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 this purpose, Orthogonal Frequency Division Multiple Access (OFDMA), capable of simultaneous data transmission and reception by multiple users (MU) has been adopted [1]. In this paper, we developed an analog/digital mixed large-scale integration (LSI) [2] compatible with 802.11ax specification to evaluate the system throughput performance of Uplink (UL) OFDMA. We evaluate and validate the throughput characteristics of 802.11ax UL OFDMA using the evaluation board on which this LSI is mounted. The simulation and evaluation results indicate the effectiveness of UL OFDMA over conventional single user (SU) communication scheme. The system throughput was measured using the developed LSI and 802.11ax UL OFDMA was found to be improved by 2.1 times when compared with 802.11ac.","PeriodicalId":201848,"journal":{"name":"2018 IEEE Global Communications Conference (GLOBECOM)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115705002","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}
