Wi-Fi fingerprint-based localization systems are widely used for indoor localization as it only needs Wi-Fi network infrastructure that exists almost everywhere nowadays. However, it can be vulnerable to environmental change if Wi-Fi fingerprint-based localization system uses fixed Wi-Fi fingerprint database as training dataset and has no method for updating training dataset. In this paper, we propose AR-WFL system including update phase that can reflect environmental change periodically and prevent performance degradation. The proposed AR-WFL system is based on crowdsourcing and no dedicated annotator exists. In addition, we adopt active learning scheme with uncertainty selective sampling algorithm to maximize cost-efficiency of the update phase. We evaluate the performance of the update phase as location estimation accuracy using a dataset we collected for 2 months. It shows that average accuracy is increased by 1.83%p using update phase with uncertainty sampling algorithm compared with the system without an update phase.

This paper proposes a method of implementing a NIC (Network Interface Card) capable of data processing at 40Gbps. Recently, technologies such as cloud services, mobile, and big data have been developed and more and more traffic is increasing. Therefore, network equipment capable of processing such traffic at high speed is attracting attention. We developed a network card based on the TILE-Gx36 processor, which made it possible to process data at high speed. As a result of our experiments, we confirmed that data transmission and reception are working normally at 40Gbps.

Radio astronomy correlator shows its significance in astronomical measurements. However, computational cost presents a barrier because of the increasing of the array size as well as the number of antennas. So the correlators which deal with signals coming from all the antennas are extremely computationally intensive process. Efficient usage of hardware should be explored in order to meet this computational challenge. This paper focus on the most computationally expensive parts in radio astronomy correlator and accelerate it using single FPGA. Results shows that the proposed hardware designs speed up the computation by at least 150 times compared with single thread CPU implementation, and at least 4 times compared with FPGA design without optimization. The throughput of our design is also higher than fully parallel CPU solution for at least 10 times, and defeats FPGA implementation without optimization in most cases.

Recent studies show that features from deep layers of convolution neural network can represent the image more strongly. This paper proposes an effective retrieval system to achieve a grading retrieval which contains two stages. In the first pre-screening stage, we propose a novel method to generate both deep binary feature vectors and compressed vectors based on multiple deep layers. And the second refine-retrieval stage refine the retrieval result. Grading retrieval can make full use of the features extracted from different layers. And, the retrieval efficiency is guaranteed by binary features and compressed features in both stages. Experiment based on public retrieval datasets shows that the proposed system markedly improves the retrieval accuracy while enhancing the retrieval efficiency.

This paper discusses a solution for digital universities to extend the functionality of their e-learning platforms to improve, not only their delivery model of instructional content, but also their way of assessing the knowledge of the students. Indeed, this paper proposes a solution for the platform of Moodle, allowing to create virtual classes, integrating the sharing and the control of screens, the transfer of files independently of their type and their size, the video, the audio, chat, different actors. This solution integrates an audio and video knowledge assessment tool for language lesson modules and enables learners to learn to communicate. Our solution is built around MSRP and WebSocket protocols, is used directly with current browsers as well as computers, smartphones and tablets. Our solution has allowed, among other things, language teachers and STEM to perform work online and face-to-face as it should without necessarily resorting to the MCQ or be obliged to modify the tests to take into account the difficulties related to the evaluation of programming and networking lessons.

Network security has become a critical issue in recent years. A drastic increase in the use of devices for accessing corporate networks could expose these systems to major security risks. As the use of personal computers moves to mobile devices and now IoT devices, it is highly desirable to gain more services and more accessible channels for corporate information. In addition, the scope and definition of IoT security have changed from time to time in response to technology changes and market needs. This paper presents a review of recent challenges, trends, and concerns related to IoT security, and discusses three generations of IoT security from past to future. IoT service platforms, values created out of customers' transaction data, industry and market driven approaches, the replacement of smartphone or BYOD, and IoT policies will all become more important.

Wi-Fi become the more popular wireless technology in our living environment. More than one wireless access point to assemble a wireless distribution system is not exclusive to the enterprise. However, current Wi-Fi protocol has no central control mechanism and efficiency cooperation mode between different wireless access points. In this research we proposed a wireless distribution system with software define network controller which provide the following properties. First, this system separates the control plane and data plane with different wireless interfaces. Second, different traffic flows from one access point to another could be assigned with independent, non-mutual interference channels if wireless resource is enough to achieve high throughput performance for whole wireless system. Third, the SDN controller is centralized unit and could execute the global channel optimization rather than regional channel optimization between two adjacent wireless access points. This system facilitated current wireless infrastructure to build the control plane. It utilizes the central Software Defined Networking (SDN) controller to collect required information from different access points, distribute resources to different access points and control the traffic flows. We demonstrate how wireless system with a central control unit could enhance the channel optimization and improve the whole system performance. Experiment to verify our idea is completed by Network simulation 3 (NS-3). The result shows with reasonable channel assignment, the wireless distribution system could optimize all wireless access points interfaces.
Wi-Fi成为我们生活环境中越来越流行的无线技术。多个无线接入点组装无线分配系统并不是企业所独有的。然而，目前的Wi-Fi协议没有中央控制机制和不同无线接入点之间的高效合作模式。在本研究中，我们提出了一种具有软件定义网络控制器的无线配电系统。首先，采用不同的无线接口将控制平面和数据平面分离。其次，如果无线资源足够，可以为从一个接入点到另一个接入点的不同业务流分配独立的、互不干扰的信道，以实现整个无线系统的高吞吐量性能。第三，SDN控制器是集中式单元，可以在相邻的两个无线接入点之间执行全局信道优化，而不是区域信道优化。该系统促进了当前无线基础设施来构建控制平面。它利用中央SDN (Software Defined Networking)控制器从不同的接入点收集所需的信息，将资源分配到不同的接入点，并控制流量。我们演示了具有中央控制单元的无线系统如何增强信道优化并提高整个系统的性能。通过Network simulation 3 (NS-3)完成了验证我们想法的实验。结果表明，通过合理的信道分配，无线分配系统可以优化所有无线接入点的接口。
