Maximizing Multicast Throughput in a Single-Hop Multi-channel Wireless Network
David Robert Wasserman, Douglas S Hulbert · 2014
This paper studies multicast traffic in a wireless network in which all nodes are within communication range of each other and share multiple independent channels. A node in this network cannot simultaneously transmit and receive, and can only transmit on one channel at a time, but when not transmitting it can simultaneously receive all channels. It is shown that increased throughput may be achieved by using erasure coding, which eliminates the requirement that all recipients listen at the same time. For any given set of multicast sessions, throughput may be optimized subject to a fairness constraint by solving a certain linear programming problem.
