Impacts of Repetitions and Segment Size Variability on Object-Level Throughput in T-DMB

Data services in terrestrial-digital multimedia broadcasting (T-DMB) inherently have the disadvantage of retransmitting data unnecessarily for reliability. This paper proposes a novel optimized transmission policy using segment size and repetition number variability, which maximizes the object-level throughput. The theoretical modeling and simulation results demonstrate that our policy provides a throughput gain over the conventional protocol.
