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}

This paper proposes a novel spatially adaptive linear precoder and explores its performance, alongside classical Zero-Forcing Precoding (ZFP) and Tomlinson-Harashima Precoding (THP) methods, under two distinct scenarios. In this paper, the objective function is set to maximise the aggregate capacity of the copper MIMO channel. All precoding methods benefit from a coordinated bitloading to maximise the spectra within a defined power spectrum density (PSD) mask. Results suggest that THP's superiority is substantial in the fixed cable length scenario whilst the proposed Spatially Adaptive Generalised ZFP (SA-GZFP) outperforms the latter marginally in the dendritic one. The paper further suggests that a spatially adaptive nonlinear precoder may have the potential of combining the gains of THP and Maximal Ratio Transmission (MRT) for greater system performance.","PeriodicalId":201848,"journal":{"name":"2018 IEEE Global Communications Conference (GLOBECOM)","volume":"17 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":"115573733","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 particular, the non-orthogonal multiple access (NOMA) is incorporated to further improve the system spectrum efficiency and we assume the base station only knows the statistical channel state information of the users. To evaluate the performance of the HARQ-CC enabled NOMA system, we first analyze the outage probability of each user. Then, based on the derived outage probabilities, by optimizing the transmit power, an average power minimization problem is considered. However, the attained expressions of the outage probabilities are nonconvex and extremely complicated, and thus make the formulated problem difficult to deal with. To efficiently solve the original problem, we first conservatively approximate it by a tractable one and then use a successive convex approximation based algorithm to handle the relaxed problem iteratively. And the presented algorithm can be guaranteed to converge to at least a stationary point of the problem. The simulation results show the efficacy of the proposed transmission strategy and the near-optimality of the proposed approximation approach and algorithm.","PeriodicalId":201848,"journal":{"name":"2018 IEEE Global Communications Conference (GLOBECOM)","volume":"20 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":"115591092","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}

As a consequence, the industries are gradually being shifted towards a shared storage software defined data center (SDDC) platform, where all the resources like computing, storage and network are virtualized within a single box and managed by a single controller. However, with such kind of shared storage architecture, network can be a performance bottleneck, as the network also needs to carry the storage workload. Because of this reason, virtual machine (VM) migration over a started storage SDDC platform can be an issue in the presence of storage workload. In this paper, we provide a thorough performance study of VM migration performance over shared storage SDDC platform under various different types of workloads. We first discuss a methodology to develop a shared storage SDDC platform using open source softwares and tools, and then perform thorough experimentation of VM migration performance in terms of application quality of service (QoS) under various different workloads. We observe that VM migration with either network or storage workload may get affected due to shared storage data synchronization over the network. From this performance analysis, we conclude that although shared storage SDDC provides a flexible, cost-effective, energy-efficient and easy-manageable solution for data centers, there are multiple performance bottlenecks that need to be addressed for getting the best out of it.","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":"124121744","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 every time slot, users choose a layer randomly and independently of other users. Each layer corresponds to a code book, and users in each layer utilize the same code book and perform power control such that they have the same received power level at the Access Point (AP). Users of the same layer also choose the same pilot sequence that is transmitted with their code word, together with all users from other layers. The AP uses the pilot sequences to detect the layers selected and estimate the number of users in each layer. Using this information, the AP first separates the codewords corresponding to the different layers. Then, users of the same layer are decoded jointly. Based on this, we formulate an optimization problem to find the power levels that maximize the reliability of the system, i.e., the probability that an arbitrary user is decoded successfully, subject to some power and decoding complexity constraints. The problem is found to be non-linear and very complex. We propose some approximations that allow us to use mixed-integer linear programming (MILP). Numerical results show that the multi-layer setup can support a larger load with higher power efficiency for the same reliability and decoding complexity requirements.","PeriodicalId":201848,"journal":{"name":"2018 IEEE Global Communications Conference (GLOBECOM)","volume":"131 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":"114338938","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}
