Abstract
Broadcasting mechanisms have been widely used to transfer information to a large number of clients. Information is transferred by broadcast servers (satellites or base stations) downstream with a wide bandwidth. Most of the broadcast schemes try to minimize the average “access time”. This paper presents a real-time broadcast algorithm that transfers many information items including one with timing constraint. Our real-time broadcast algorithm attempts to meet the deadline for real-time information as well as to minimize the average access time for non-real-time information. Simulation results show that our algorithm can reduce the average access time for the non-real-time information while meeting the deadline for the real-time information.
