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 […]

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, […]

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 […]

Delay‐ or Disruption‐Tolerant Networking (DTN) is a communications approach that is utilized in easily disrupted or delayed networks. Examples of such networks are often found in heterogeneous networks, mobile or extreme terrestrial networks, and planned networks in space. In this paper, we examine the metropolitan bus network as a research target of DTN for a […]

The wireless resources required by users have increased in parallel with and above improvements in WLAN technology, requiring even more accurate and practical resource management. Research on medium utilization, which is fundamental to resource management, has supplied insufficient evidence to apply it in real environments. This paper proposes a hybrid measurement approach to medium utilization […]

The Wi-Fi based broadcasting system is mobile Internet Protocol Television(IPTV) technology, which transmits the multimedia content to a lot of local mobile users in real time. Unlike conventional Wi-Fi based multimedia streaming systems that use a separate unicast packets to serve each user, the Wi-Fi broadcast system uses the broadcast packets for scalability because one […]

A Wi-Fi broadcasting system is a kind of Mobile-TV system that transmits multimedia content over Wi-Fi networks. The specialty of the system is that it takes advantage of broadcast packets for streaming to be scalable to the number of users. However, the loss rate of broadcast packets is much higher than that of unicast ones […]

Recently, there has been an increase in user interest in multimedia services, such as VoIP, using mobile stations equipped with the IEEE 802.11 Wireless Local Area Network (WLAN) module in fast moving environments like Vehicle Ad hoc Networks (VANETs). In order to provide mobility and guarantee bandwidth in a wide area, a handoff among access […]
