 Obiettivo del progetto (Objective)

'Communicating multimedia content such as high-quality images, audio or video streams became a part of everyday life both for the purpose of business and entertainment. As user mobility and need for multimedia content available anytime and anywhere increases, multimedia applications such as video streaming, mobile TV, video-conferencing, multimedia peer-to-peer networking, social networking with multimedia content, interactive gaming, etc., are becoming a major bandwidth consumer on small, handheld, mobile devices and are indicated in many recent studies as a major driving factor for the next generation mobile broadband technologies. This is evident both in the user equipment such as smart phones, portable digital assistants and tablets, for which the screen size and resolution is ever-increasing and constrained only with the comfort of the device usage, as well as in the development of the fourth generation high-speed wireless data interfaces such as Mobile WiMax (IEEE 802.16e-2009) and 3GPP LTE-Advanced that aim to provide sufficient data rates for comfortable high-quality mobile multimedia services. Recently introduced groundbreaking information-processing paradigm called network coding opens a novel set of possibilities for improvements of network performance in terms of throughput, reliability and delay. However, even though it usually provides more bandwidth, a number of problems arise in successful integration of network coding principles into multimedia communications in current wireless communication systems. This proposal aims to address the problem of design of efficient network coding schemes for scalable multimedia delivery in wireless networks. The goal of this project is to provide both rigorous theoretical and realistic system-level investigation of network coded scalable multimedia transmission in emerging wireless broadband systems.'

Introduzione (Teaser)

Communicating multimedia content such as images, audio or video streams has become an integral part of everyday life, both for business and entertainment purposes. An EU-funded project explored networking problems in delivering multimedia data over emerging wireless networks.

Descrizione progetto (Article)

Information is increasingly becoming available anytime and anywhere. Use of mobile technology, especially for video streaming, mobile television, video conferencing, peer-to-peer networking and interactive gaming, has been gaining widespread use over the last few years.

Consuming a major part of network bandwidth, such applications have been considered the main driving force behind next-generation mobile broadband technology. Mobile WiMAX, Long-Term Evolution (LTE) and LTE Advanced are mobile Internet standards that provide sufficient data rates for high-quality mobile multimedia services.

Network coding is a new paradigm in information processing that opens possibilities for improving network performance in terms of throughput, reliability and delay reduction. Despite its potential to increase bandwidth efficiency, wireless communication systems based on network coding suffer a number of issues in supporting access to multimedia data.

The EU-funded project MMCODESTREAM sought to address the challenges associated with designing efficient and scalable network coding schemes for wireless multimedia transmission. The research placed focus on unequal error protection schemes for reliable multimedia delivery, and design and analysis of multimedia delivery services over LTE and LTE Advanced. Research was also geared toward other novel topics such as coded random access protocols in wireless networks.

Project research has advanced the state of the art in efficient multimedia transmission over next-generation wireless networks. The initiative also resulted in 13 peer-reviewed scientific publications and presentation of 17 papers at many international conferences.
