Rateless coding for multicasting multimedia over wireless channels
EF 2008-09
Résumé
In recent years, the use of advanced communications devices has become pervasive. The wireless
telecommunications sector plays a critical role in the Canadian economy, accounting for 25,000 jobs, over $9.5
billion in revenue, and a $4.1 billion investment in infrastructure. In recent years, the number of wireless
subscribers has increased at a compound annual growth rate exceeding 17% to reach 14.9 million while
revenue has grown at a rate of 14% to reach $9.5 billion. Not only is the number of mobile phones surpassing
the number of wired phones, the functionalities of these mobile devices have multiplied to include the
transmission of still images, data, software applications and video. This has led to many positive societal
developments both in Canada and worldwide, including increased security, social interaction and the removal
of other barriers from low-cost, accessible information distribution.
For the above growth to continue, wireless communications networks need to undergo a significant redesign.
While the underlying principles of telecommunications networking have traditionally involved layering as
developed for wire line systems, the plethora of mobile/handheld devices necessitates breakthroughs in
spectral, energy and economic efficiency since these layered protocols can be extremely inefficient for small,
low-power devices operating over wireless channels. The proposed project is concerned with the design of
coding methods to enable efficient distribution of information to large numbers of futuristic mobile devices and
network topologies, including those involving relaying and cooperation. The aim is to support both data as well
as other media content. Relative to data, media in the form of audio and video can tolerate packet loss much
more than transmission delay. This project proposes to investigate new transmission protocols enabled by
advances in rateless fountain codes to avoid the costly overhead associated with current retransmission
protocols that reduce bandwidth and add to delay and traffic congestion.
