Multi-antenna receive combining has the promise of alleviating the impact of interference, translating to improved connectivity performance. In this paper, we evaluate the performance of Conventional Beamforming (CB) and Maximum Ratio Combining (MRC) receivers for UAV communication based on live Long Term Evolution (LTE) networks. Our measurement setup consists of nine Universal Software Radio Peripheral (USRP) boards and a circular antenna array with sixteen elements. The LTE signals are recorded at different UAV flight heights in urban environments, and processed offline. Results show similar Signal-to-Interference-plus-Noise Ratio (SINR) performance by MRC and CB, with CB slightly outperforming MRC provided knowledge of LTE signal structure is used for the beam selection. No significant dependency from the flight height has been observed. The outage probability analysis further emphasizes the benefits of using CB in the studied scenarios.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"174 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":"116126787","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}

Unmanned aerial vehicles (UAVs) also attracts more attentions these years. However, the limited battery of both MTC devices (MTCDs) and UAVs constrains the deployment. Besides, the limited computation capacity of MTCDs also impacts the network optimization in mMTC networks. In this paper, UAV-based aerial base station is deployed to collect data and provide computing service for MTCDs. We introduce a non-service-tolerant parameter and propose a hybrid hovering positions selection (HHPS) algorithm. The hovering positions of UAV with the minimum power consumption of MTCDs are selected. Furthermore, We propose a trajectory planning method based on Cuckoo Search (CS) algorithm. The energy consumption and the throughput of UAV, the latency of MTCD tasks and collecting and computing efficiency with different priorities are optimized. Simulations are carried out to illustrate that the proposed HHPS algorithm and trajectory planning algorithm have superior performances compared with existing works.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"75 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":"114993448","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}

One way to optimize their usage is to make them demand-driven depending on human occupancy. This paper focuses on accurately estimating the number of occupants in a room by leveraging multiple heterogeneous sensor nodes and machine learning models. For this purpose, low-cost and non-intrusive sensors such as CO2, temperature, illumination, sound and motion were used. The sensor nodes were deployed in a room in a star configuration and measurements were recorded for a period of four days. A regression based method is proposed for calculating the slope of CO2, a new feature derived from real-time CO2 values. Supervised learning algorithms such as linear discriminant analysis (LDA), quadratic discriminant analysis (QDA), support vector machine (SVM) and random forest (RF) were used on several different combinations of feature sets. Moreover, multiple performance metrics such as accuracy, F1 score and confusion matrix were used to evaluate the performance of our models. Experimental results demonstrate a maximum accuracy of 98.4% and a high F1 score of 0.953 for estimating the number of occupants in the room. Principal component analysis (PCA) was also applied to evaluate the performance of a dataset with reduced dimensionality.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"9 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":"123738337","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 cooperative awareness service will give vehicles the capacity of being aware of the neighborhood through the periodic dissemination of beacon messages, carrying mobility information. Applications like these need a wireless technology able to provide high reliability and low latency. In this context, Cellular-V2X based on long term evolution (LTE) Release 14 is a promising candidate. Objective of this work is to focus on LTE Sidelink mode 3, where resources reserved to direct links are managed by the network and to propose a resource scheduling algorithm based on the knowledge, with different levels of accuracy, of the positions of the vehicles at the network side. Through simulations, carried out in realistic highway and urban scenarios, we compare the proposed solution with a benchmark algorithm based on the concept of reuse distance and we demonstrate that the new solution, other than always offering the highest performance in terms of packet reception ratio and latency, does not require the fine tuning of any parameter.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"41 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":"122938890","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 the number of IoT devices in health care system is increased exponentially, the privacy and security issues of patients are becoming a concern. In order to protect personal and device-generated information, we propose to use blockchain-based smart contracts for managing patients' information and medical devices. In detail, using blockchain based on the Ethereum protocol, we create a remote healthcare system including healthcare provider (such as hospital), healthcare professionals (doctors) and patients. Health condition of patients is measured by sensors and such information is written into blockchain automatically. In addition, we propose a processing mechanism to store the medical device information efficiently and sparingly in accordance with health situation of patient. Concretely, we filter the data from sensors before deciding whether to write data into blockchain or not. Doing so we can reduce the size of blockchain as well as save amount of coins for transaction efficiently. However, the abnormal data from sensors will be written to blockchain immediately and trigger an emergency contact to doctor and hospital for on-time treatment. We have verified the proposed smart contract on Ethereum test environment called TESTRPC and implemented the system on an experimental environment with real devices. This system works well at small scale.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"47 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":"125399719","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 the big-data era, the size of the content space is essentially infinite. Moreover, users with common features typically share similar content preference. In order to address these issues, we model the wireless caching problem as a contextual multi-armed bandit (CMAB) problem that considers the infinitely arms, and propose a Monte-Carlo tree search aided contextual upper confidence bound (MCTS-CUCB) algorithm, to make accurate content caching with low complexity. Specifically, we introduce a tree-based search method to analyze the content subspace instead of a single content, thereby reducing the computing load. In the search process, a cover tree is built in an incremental and asymmetric manner, which can reflect the users' content preference. Besides, contextualization allows to learn content preferences for groups of users having similar contexts, which significantly accelerates the learning process and improve the cache hit rate. Our simulation results on a real-world data set (MovieLens 1M Dataset) demonstrate that the proposed MCTS-CUCB algorithm is capable of achieving a considerable reduction in complexity compared with the existing related algorithms with a superior cache hit rate performance.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"30 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":"125550429","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}
