Since the heterogeneous Internet Service Provider (ISP) router policies prevent the quality-of-service (QoS) multimedia applications which require IP layer multicasting from being widely deployed on the Internet, the mechanism of implementing such applications by application layer broadcasting through organizing the multicast group in a peer-to-peer overlay network is proposed. In this paper, we study...
The developments of network infrastructures and personal intelligent devices, e.g., smart phones, makes the multimedia related services play an important role in network user applications. However, users are still troubled by limited bandwidth, burst of incoming service requests, and imbalance of content dissemination while enjoying the multimedia services. In this paper, we proposed a user grouping-based...
In this paper, we present a novel idea of multipath multicast, which is imperative to bandwidth intensive applications, in the context of multimedia streaming. In addition to congestion control, multipath TCP (MPTCP) has been proposed to establish multiple paths in a network to improve network reliability. Application-layer multicast (ALM) has been proposed to leverage end systems instead of dedicated...
Nowadays, Information and Communication Technology (ICT) is widely used in various fields. For an example, education sector also widely utilizes ICT in distance learning process through the use of multimedia conferencing technology. In order to support the multimedia-based services, it is needed sufficient network resources such as good infrastructure and bandwidth availability. In Indonesia, most...
With the advent of new technologies every day and with each technology more bandwidth intensive than the previous, The need for some transformative technology to coop with the bandwidth problem is ever growing. The current technologies like LTE uses MIMO, OFDM and coding techniques that have reached their limits and provide an almost theoretical efficiency but they also in the near future may be uanble...
According to the Convergence of a vehicle and IT, In-Vehicle-Network (IVN) is complicated and the multimedia data is increased. Ethernet guarantees Quality of Service (Qos) of the existing Control Area Network (CAN) communication and has a high bandwidth. As a result, the Ethernet is recently developed a new standard. IEEE 802.1 Audio Video Bridging (AVB) supports to handle priority and queuing for...
Opportunistic Network has become an international hotspot in according with the popularity of various mobile intelligent terminals. But the nodes with limited communication capabilities cannot satisfy the growing of large content data transmission. Aim to these issues, we propose a novel communication capacity calculation model of Opportunistic Network based on the classical Random Direction mobile...
This paper will discuss about transmission of multimedia content in limited capacity network (up to 5 Mbps), especially to study about the impact of background traffic towards multimedia content delivery quality in a limited capacity network. Observation methods proposed in the study include measurement of limited capacity network, background traffic modeling, and simulating the network to observe...
Research about multimedia streaming in cognitive radio network has become a hot issue recently. In order to enhance the throughput of real-time multimedia streaming and maximize the utility, we proposes a dynamic spectrum allocation strategy based on Qos-layering and auction theory (QLAS). In this strategy, we classify the secondary users according to the feature of data stream, and choose the optimal...
Considering that the current information content being exchanged is increasingly multimedia, it is quite natural to the demand for a relatively short time downloading or to a certain extent uploading large information files to the Internet. Mobility is increasingly demanded along with broadband. Certain to locations do not have the necessary infrastructure for broadband. Users that are residing in...
The cloud computing technology gradually brings every service online that makes all data and information of services is stored in cloud storage. However, there are real-time services such as multimedia streaming and emergency notification that require sensitive response and low latency. Regarding of the cloud computing, the data transmission between the end-users and the cloud significantly increases...
The migration of popular Catch-up TV services to modern Over-The-Top (OTT) multimedia delivery infrastructures creates a wide set of scalability challenges which are commonly addressed using Content Delivery Networks (CDNs) relying on caching nodes close to users.
This paper presents some end to end measurements of multimedia services carried out in the frame of LTExtreme project. We provide some understanding of the main parameters and the role of the different protocol layers in the achievement of the desired Quality of Experience (QoE). The trade-offs related to the adaptation algorithms that have been tested in a demonstrator are discussed, showing that...
Millimeter-wave (mm-wave) communication is a promising technology for the next generation cellular networks. Motivated by the huge available bandwidth at these bands, it can be used to support the fastest-growing demands for the mobile data traffic such as multimedia applications. However, there are some challenges on the network connectivity at the mm-wave frequency bands. The high path loss, the...
In emergency scenarios, e.g., natural disasters, the infrastructure of telecommunication system is partially or even completely disrupted. While the bandwidth and energy resources of system are limited, the maltimedia communication demand of myriad usen may reach the peak of data traffic. This in tum makes the system more challenging to serve the users high quality of maltimedia streaming with con...
In Video-on-Demand system, periodic broadcasting is the most bandwidth-efficient method to provide clients with popular videos. Many broadcasting schemes have been proposed to reduce server's bandwidth as well as client's waiting time. However, most of the schemes assume clients to have enough reception bandwidth, which is impractical since client's reception bandwidth varies, especially in wireless...
Video-on-demand (VOD) system allows users to access media any time without the need to leave their home. Hard disk drive (HDD) has become popular for VOD storage to store and deal with a large amount of data. In practical cases, disk storage throughput is limited by a slow HDD and disk operating degrades drastically when the server needs to serve many simultaneous video streams. On the other hand,...
Multimedia streaming services in vehicular ad-hoc networks (VANETs) became a focus of many researchers. Achieving stable and high streaming rate under the high dynamic topology is considered a major challenge in such networks. Several approaches have been proposed to improve the existing routing protocols. However, some protocols ignore the QoS requirements needed for VANET safety and multimedia services...
While the demand of video streaming services (VSSs) over the mobile networks have been soaring, the capacity of wireless links cannot keep up with the traffic needs. The difference between traffic demand and the link capacity, together with time-varying link conditions, causes inadequate service quality of video streaming, such as long buffering delays and sporadic disruptions. In this paper, by leveraging...
Mission Critical Communications and Services are of a special nature that needs special requirements. Therefore, there are many challenges that face implementing mission critical communication system over commercial mobile communications networks. Signaling of SIP messages in the access technology domain and IMS domain needs enhancement to ensure meeting the mission critical service requirements....
