Multimedia meet next-generation wireless networks
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.
