In this thesis, the problem of transmitting data in the form of multicast and
broadcast traffic has been studied. The traffic can be from a real-time appli-
cation which has a short block length or it can be a general broadcast traffic
in an ad-hoc network. The goal is to reduce the total number of transmis-
sions which results in reducing the delay and improving the energy efficiency
of the system. Toward this goal, network coding and fountain-codes solutions
are studied in this thesis. For the case of broadcasting, a new fountain-code
method is proposed. Our results show that this method increases the energy
efficiency compared to other methods that have the same order of complexity.
For the case of multicasting, we provide a finite block length analysis on the
effect of erasure on overhead. We use this analysis to investigate a method of
packet construction along with using fountain codes. -
