Multicast Outage Probability and Transmission Capacity of Multihop Wireless Networks

Multicast transmission, wherein the same packet must be delivered to multiple receivers, is an important aspect of sensor and tactical networks and has several distinctive traits as opposed to more commonly studied unicast networks. Specially, these include identical packets must be delivered successfully to several nodes, outage at any receiver requires the packet to be retransmitted at least to that receiver, and the multicast rate is dominated by the receiver with the weakest link in order to minimize outage and retransmission. A first contribution of this paper is the development of a tractable multicast model and throughput metric that captures each of these key traits in a multicast wireless network.
