Multimedia Streaming for the Future Generation Mobile Networks

2003

In this work we propose and evaluate mechanisms for the multiplexing and the integrated delivery of Video and Data Traffic over a Wireless Cellular High Speed Packet Switched Network. We envision a system where the Mobile Terminals are considered to be high performance devices with extended storage capabilities which can act like cache memories streaming multimedia material. We focus on the uplink channel and we thoroughly investigate the system's performance under a variety of possible loads which consist of actual MPEG-4 streams and Data Traffic.

User requirements are growing faster than ever and the limitations of the current mobile communication systems have forced the researchers to come up with more advanced and efficient technologies. 4G mobile technology is the next step in this direction. 4G is the next generation of wireless networks that will totally replace 3G networks. It is supposed to provide its customers with better speed and all IP based multimedia services. 4G is all about an integrated, global network that will be able to provide a comprehensive IP solution where voice, data and streamed multimedia can be given to users on an "Anytime, Anywhere" basis. At present we have many technologies each capable of performing functions like supporting voice traffic using voice over IP (VoIP), broadband data access in mobile environment etc., but there is a great need of deploying such technologies that can integrate all these systems into a single unified system. 4G presents a solution of this problem as it is all about seamlessly integrating the terminals, networks and applications. The race to implement 4G is accelerating as well as quite challenging. The aim of this paper is to highlight the benefits, challenges in deployment and scope of 4G technologies.

High quality and sustained multi media experience is expected to be a major feature of the Future Mobile Internet (FMI). Currently deployed novel mobile network technologies such as LTE (Long Term Evolution) make use of the Internet and its best-effort TCP/IP protocol stack to enable applications. The orientation towards TCP/IP is logical due to the success of the Internet. However, TCP/IP still provides almost no support for Quality of Service (QoS). Hence, it seams to be a contradiction that high quality services can be reached by TCP/IP.

The convergence of telecommunications, computing, and content industries has been one of the major trends during recent years. The convergence has led to the creation of a wide range of multimedia services that are available in digital form through the Internet. There is a need for user and terminal mobility supporting both personal communication and multimedia services on top of the Internet. To help meet this need, this paper presents ongoing research on the Fourth Generation (4G) roaming and mobility model. The 4G model is compatible with existing IP standards. The basic elements of the model are described and the model is compared to the GSM (2G) model.

boiling Four Generation (4G) networks are the far the can support since it airwaves over the connection geographic distance over the world, especially are to the popularity of the wireless devices. The Long-Term Evolution (LTE) is often called the 4G. Nowadays, telecommunications, video traffic has burgeoned under the development of LTE, the truly underlying access technology of 4G networks. During LTE deployment, different transport protocols are the most recommended and widely studied such as Transmission Control Protocol (TCP), User Datagram Protocol (UDP) and Datagram Congestion Control Protocol (DCCP), which can perform differently on 4G networks depends on the network's scenario as well as parameters setting. Although the LTE deployment is rapidly apace, there is a lack of performance evaluation of its protocols. Therefore, an extensive analysis is needed to evaluate the performance of various protocols for high end applications like multimedia applications. Supporting these multimedia applications with varied quality of service (QoS) requirements while maximizing the resource utilization is a challenging task. To achieve the objective of this study, this work tries to answer the following questions: are the old protocol suit with this new technology; which one has the best performance and; which one has the greatest effect on throughput, delay, packet loss and packet delivery ratio. In this study, our analysis and compare are on the performance of different the Internet transport protocols for streaming video via using simulation environment. Through the Network Simulation 3 (NS3), the performance of transporting an MPEG4 video stream, including throughput, delay, packet delivery ratio and packet loss are analyzed at the base station through TCP, UDP, and DCCP protocols over 4G-LTE technology. The results show that DCCP has a better throughput, and a lesser delay, but at the same time it has more packet losses than UDP and TCP. Based on the results, DCCP is recommended as a transport protocol for real-time video.

This paper seeks to provide challenges in mobile multimedia communication together with engineering perspective. It is known that advent of powerful hand-held devices and the desire for communication on the move are driving forces behind an engineering mobile technology. Quality of service (QoS) including the corresponding infrastructure presents the framework toward next-generation wireless networks. The goal is to analyze network mobility issues ad requirements in the context toward the fourth generation (4G) networks. In the first part of this article, we deal with key drivers in mobile multimedia including technologies overview. The second part gives quality of service requirements and challenges including the network infrastructure.
