Abstract
With the aim of understanding network coding in wireless scenarios, we investigate multicasting in Aref networks. These networks do not capture interference, but they do incorporate deterministic broadcasting. We characterize the multicast capacity of Aref networks, the achievability of which is shown using an ensemble of random codes. In order to construct structured capacity achieving codes, we consider a natural layered coding scheme and show that this coding scheme is suboptimal.
