This paper proposes an accident prevention system between vehicle and pedestrian using YOLO (You Only Look Once) and depth camera. Based on the recognition information of lanes and pedestrians using YOLOv2-tiny based on deep learning, when a pedestrian enters the roadway, it notifies the user of the crisis situation in advance. Since the algorithm...
Conference Paper
Internet of Things (IoT) imparts not only comfort to our life but also exposes new research areas like Social Internet of Things which can assist to manage things more efficiently. Another concept, Blockchain, is imparting in every research area because of its technology. In this context, the contribution of this paper follows: 1) we depict popular...

This paper presents a performance analysis for watermarking to assess the quality of watermarked image after process of watermarking. Comparison of two different watermarking techniques i.e. Discrete Wavelet Transform (DWT) in combination of Singular Value Decomposition (SVD) and Redundant Discrete Wavelet Transform (RDWT) in combination with Singu...
Article
We present a novel interference free dual-hop cooperative spectrum sharing protocol in cognitive radio networks exploiting spatial modulation (SM) at both primary transmitter (PT) and secondary transmitter (ST). A ST equipped with multi-antenna acts as a half-duplex decode-and-forward relay for the primary system. During phase-1, SM is invoked at P...
Article
Recently, the Smart household appliances to provide Smart services have been actively spreaded by providing IoT(Internet of Things). Also, the appliances which Wi-Fi and Bluetooth can directly control are preferred. But until now, the most household appliances are based on IR(InfraRed) and the each procotols of them are different. In this paper, to...

Light Emitting Diode (LED) is quickly becoming the latest technology in the application of lighting on streets. By combining the concept of Internet of Things (IoT) and LED streetlight, this paper aims to apply the concept of microservices architecture so that the development process can be agile and scalable on demand. This paper also describes th...

In this paper, a capsule body shaped surveillance/monitoring device is developed. The device includes a camera and GPS module to transmit live video data and real time GPS coordinates respectively using the Intel Edison module. A control application is developed for the smart phones and tablets to wirelessly view the live video stream and location...
Conference Paper
Lead-acid battery is widely utilized to provide electricity in vehicle. There are dozens of system is used the lead-acid battery for power supply e.g., in electric car, mobile robot, electric forklift, etc. Nevertheless, overuse could significantly effect on life time of battery. In this paper, remote monitoring of lead-acid battery for electric fo...

In this paper, performance of IEEE 802.11 carrier-sense multiple access with collision-avoidance (CSMA/CA) protocols in saturated traffic conditions is presented taking into account the impact of imperfect channel sensing. The imperfect channel sensing includes both missed-detection and false alarm and their impact on the performance of IEEE 802.11...
Article
This paper proposes the possibility which the fuzzy theory can be used to improve the performance of the parabolic SAR(Stop-And-Reverse) indicator in the trading systems for stock market. The simulation results with data of the KOSPI 200 future show that the occurred number of trading signals and the false signals in the proposed fuzzy SAR indicato...
