The emerging wireless media delivery services have placed greater demands for wireless networks to support high-throughput applications while minimizing the delay of individual packets. In this paper, the authors investigate using inter-session network coding to send packets wirelessly for two deadline-constrained unicast sessions. Specifically, each unicast session aims to transmit a stored video file, whose packets have hard sequential deadline constraints. They first characterize the corresponding deadline-constrained capacity region under heterogeneous channel conditions and heterogeneous deadline constraints.
