Awareness of obstacles such as debris, potholes, construction site, and traffic movement pattern improve mobility and independence of them. To address this problem, we implemented an interactive and portable sidewalk assistive device (IPSAD). The key idea is to use the power of deep learning to model the “obstacles” on a sidewalk to provide personalized feedback to the user. We focus on transfer learning and fine tuning of pre-trained Convolutional Neural Network (CNN) models for real-time obstacle recognition that can be deployed in small form factor devices. This approach also account for issues related to the execution time and energy efficiency. We empirically evaluate a number of state-of-the-art architectures to choose the best model based on fewer parameters and lower energy consumption. Finally, we built fully integrated IPSAD prototype on Raspberry Pi3 (RPi3). Audio feedback scheme were implemented to accommodate user preferences and personalization. We perform quantitative evaluation of the prototype system based on the accuracy of the model on Ambient Awareness on Sidewalk (AS) dataset, on-field system performance, data communication, response time (capturing images, recognition of obstacle and feedback), and failure points. Empirical evaluation showed that the accuracy of the model is 87% on the AS dataset and 78.75% on-field system. The system can operate either standalone mode when there is no Internet or cloud mode. In addition, the system can use human intelligence through crowd source and caregiver(s) to assist the users when automated system fails.","PeriodicalId":344652,"journal":{"name":"2018 IEEE International Smart Cities Conference (ISC2)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128381769","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}

However, currently available network technologies, such as 3/4G, GSM, LTE, and LTE-A, are rapidly reaching their limit mainly due to spectrum scarcity, cross technology interference and increased traffic demand. Such limitations are only going to worsen in the next years, due to the advent of Internet of Things technologies that are expected to interconnect billions of devices to the Internet. Dynamic Spectrum Access (DSA) has been proposed to overcome such limitations and exploit unused spectrum resources over multiple electro-magnetic spectrum bands. In this paper, we propose a DSA-based architecture in which DSA radio devices are deployed on the Smart City’s urban vehicles (e.g., public buses, taxis, municipal vehicles, etc.), that act as data mules to gather and forward the various types of data. This results in a Delay Tolerant Network (DTN) in which devices can operate over multiple bands, if available. Given lack of research in efficient routing schemes for such networks, we first compare existing DTN routing approaches designed for standard (or single band) DTNs, such as Epidemic Routing and Spray and Wait, in urban DSA scenarios and show that they are largely inefficient. Subsequently, we propose extensions to these approaches in order to better exploit the availability of multiple bands in a DSA paradigm. Results on realistic traces based on the map of Lexington, KY, USA, show that the modified approaches improve the network performance, such as successful message delivery and network latency, however, at the expense of very high energy expenditure and message overhead. Hence, we conclude by pointing out that further research is needed, since significant performance improvements are still possible by designing routing schemes that are specifically tailored for DSA Smart City networks.","PeriodicalId":344652,"journal":{"name":"2018 IEEE International Smart Cities Conference (ISC2)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133336172","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}

However, the IoT is inherently vulnerable to attacks. In this paper, we propose to enhance the physical layer security of the IoT by using a technique called information passing and interference addition. In the physical layer security analysis, the achieved secrecy rate has an inverse relationship with the intruder’s distance to the legitimate transmitter. The aim of our work is, first to increase the achievable secrecy rate by letting the legitimate transmitter find an alternative route to the fusion center to achieve a higher secrecy rate than the direct route. Hence, the legitimate transmitter must not disclose the actual information to the fusion center if there is an eavesdropper located between them, instead, it must pass the information to another node via a directional antenna to concentrate the power towards the intended receiving node. Passing the information to the nearest node must be done under the condition that there is no intruder in between. Second, we used simultaneous multi-stream beamforming transmission to strengthen the legitimate receiver’s signal-to-noise ratios and at the same time, it poisons the eavesdropper channel with interference. Third, the proposed node may disclose a false information to the intruder in some cases. The system has been designed and the secrecy analysis of the system has been investigated. The result showed that using directional antennas would increase the probability of having at least one secure connection coming out of the node to the other legitimate nodes by 30% than the omni antenna. Moreover, the results showed that using the simultaneous multi-stream beamforming would improve the legitimate channel’s achievable secrecy rate and that it has superiority over the directional antenna effect.","PeriodicalId":344652,"journal":{"name":"2018 IEEE International Smart Cities Conference (ISC2)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128440786","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}

Without the ability to precisely forecast their power production, integrating these sources to the electric power grid may affect grid stability. Support Vector Regression (SVR) is proven to be able to capture and deal with nonlinearity in forecasting problems. However, determining the appropriate parameters for SVR is the key issue in attaining an accurate SVR forecasting model. The objective of this paper is to forecast the output power of solar photovoltaic (PV) systems using support vector regression, of which its parameters are optimized by Cuckoo Search (CS) and Differential evolution (DE) algorithms. Real-world solar data from the 6.4kW rooftop solar PV unit located at the Advance Research Institute (ARI) of Virginia Tech in Arlington, Virginia, are used as the basis of the forecast. Six input variables are used for model development, namely day, month, hour, global normal radiation, temperature and wind speed. Model performance is evaluated using statistical indicators. Results indicate that SVR with Radial Basis function optimized by CS and DE give the most accurate forecasts.","PeriodicalId":344652,"journal":{"name":"2018 IEEE International Smart Cities Conference (ISC2)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128761401","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}
