Link Scheduling for Multiple Multicast Sessions in Distributed Wireless Networks
In this paper, the authors investigate link scheduling algorithms for throughput maximization in multicast wireless networks. According to their system model, each source node transmits to a multicast group that resides one hop away. They adopt the physical interference model to reflect the aggregate Signal to Interference and Noise Ratio (SINR) at each node of the multicast group. They present an ILP formulation of the aforementioned problem. The basic feature of the problem formulation is that it decomposes the single multicast session into the corresponding point-to-point links. The rationale is that a solution algorithm has more flexibility regarding the scheduling options for individual nodes. The extended MILP problem that also considers power control is solved with LP relaxation.
