  In this paper queue stability in a single-hop wireless multicast networks
over erasure channels is analyzed. First, a queuing model consisting of several
sub-queues is introduced. Under the queueing stability constraint, we adopt
Lyapunov optimization model and define decision variables to derive a network
coding based packet scheduling algorithm, which has significantly less
complexity and shorter queue size compared with the existing solutions.
Further, the proposed algorithm is modified to meet the requirements of
time-critical data. Finally, the simulation results verify the effectiveness of
our proposed algorithm.
