Realtime mission critical multimedia applications are targeted toward groups and are increasingly using network-layer multicast addressing to efficiently route application data, voice and video to the group members. In addition, the group members are wireless increasing the probability that multicast packets will be lost due to poor wireless conditions. This paper proposes a solution to improve wireless multicast by attempting to recover lost multicast frames at the link layer.
