R2D2 is an 18-month research project supported by EPSRC under the First Grant scheme (EP/L006251/1). Alas, it does not aspire to develop a prototype of R2D2, the famous droid in the Star Wars films. The focus of the project is on network error control and the research problem under investigation is not in the least less challenging or exciting!

The R2D2 project: Aims and Aspirations

Long-Term Evolution (LTE), the dominant system for fourth generation (4G) networks, has introduced state-of-the-art fountain coding to support wireless content streaming and downloading. Even though fountain coding can be combined with collaborative network coding to reduce network overhead and improve bandwidth efficiency, there is great scope for tailoring transceiver designs to the requirements of content distribution and for developing radically new paradigms capable of supporting high quality media in next generation systems.

The R2D2 project aims to:

  • Develop a mathematical framework to identify key relationships between various network parameters, contribute to the understanding of network dynamics and assist in the system-level optimisation of network-coded architectures.
  • Leverage the benefits of joint channel coding and network coding and propose joint transceiver designs for content delivery.
  • Delve into the emerging research field of network error correction and develop practical implementations of unified channel codes and network codes that can offer high reliability, low decoding complexity and increased security from malicious users.
