Codes and Balances: Multibeam Satellite Load Balancing With Coded Packets

Aiming to exploit the capabilities of next generation terminals to receive and process several, partially overlapping beams of a multi-beam satellite, the authors present a mathematical analysis and propose algorithms to provide enhanced and robust load-balancing to unequal load demands between beams. At the core of their mechanisms is a resource allocation problem that aims to minimize the time to deliver packets taking into account the load (traffic demands) per beam and channel conditions. Network coding is a key enabler of their mechanism, allowing a seamless and efficient exploitation of the multiple, available paths from satellite gateways to end-users and leading to a more efficient allocation of resources in each beam.
