Wireless local area network–based broadcasting techniques are a type of mobile Internet Protocol television technology that simultaneously transmits multimedia content to local users. Contrary to the existing wireless local area network– based multimedia transmission systems, which transmit multimedia data to users using unicast packets, a wireless local area network–based broadcasting system is able to transmit […]

As interest in cardiovascular disease increases, there is significant development in real-time healthcare services and devices. This paper suggests a machine learning-based arrhythmia diagnosis algorithm for mobile healthcare systems linked to a wearable electrocardiogram measurement device. The system monitors electrocardiograms in real time and distinguishes among arrhythmia, normal, and noise signals. By regular monitoring using […]

Internet of Things(IoT) technology is an global infra that offers intellectual services combined with situation recognizing knowledge and communication between humans and objects and among objects, which has become core technology in hyper-connected society with its Cloud and big data technology. To connect objects, low range and low power communication technology was needed, therefore, LoRaWAN […]

Along with the commercialization of the Internet of Things (IoT) technology, the demand for long-range, low-power and long-range, large amount of data transmission arises. However, there has been no such communication technology to satisfy the transmission. The Wi-Fi is able to send large amounts of data with its broadband technology, but because of high power […]

The Wi-Fi based broadcasting system using broadcast packets not the unicast packets of WLAN aims to provide the same quality of multimedia streaming to increased numbers of users. However, for the broadcasting packet without MAC level retransmission, packet loss is unavoidable and the place where the loss of broadcast packet occurs is not predictable. Therefore, […]

This paper is to design and implement the drone that supports wideband multimedia communication for long-range in maritime. The drone is an Unnamed Aerial Vehicle (UAV) that is controlled by a radio wave not by people boarding the machine. To develop a smart drone for high speed video streaming in long-range maritime, necessary techniques are […]

The Wi-Fi broadcasting system with its advantage of short installation time, low installation cost and broadband service, has expanded the availability throughout the places where sending large amount of multimedia data simultaneously to the majority of users is required such as classroom, stadium and meeting room. The Wi-Fi broadcasting system is composed of broadcasting server, […]

Wi-Fi broadcasting system is to offer multimedia streaming of the same quality to users even with increasing numbers of users by using broadcasting packet, not Unicast packet. However, the broadcast packet has high packet loss rate because it has not retransmission Medium Access Control (MAC) to recover the packet loss. Therefore, to prevent service quality […]
