A class of wireless multicast utility optimization problems are considered. Assume network utility is only a function of link throughput and nodes' transmission power. Under a set of physical layer assumptions, the impact of physical and data-link layer configurations to the upper layers in a wireless network can be characterized using a configuration graph. Network layer utility optimization can...
This paper shows that, under certain conditions, a wireless network can be modeled by a directed configuration graph with possible hyperarc links if the transmission schedule is given. Assume single multicast session. The maximum achievable multicast throughput equals the max-flow min-cut bound of the configuration graph. An optimization framework is proposed to maximize the multicast throughput via...
