Abstract: A source node includes a topology information extractor configured to acquire information of a channel state between nodes included in a multicast network, and extract topology information of the multicast network. The source node further includes a relay node selector configured to select, from the nodes, a relay node to relay a packet transmitted from the source node, based on the topology information.

Abstract translation: 源节点包括拓扑信息提取器，被配置为获取组播网络中包含的节点之间的信道状态信息，并提取组播网络的拓扑信息。 源节点还包括中继节点选择器，其被配置为从节点选择中继节点，以基于拓扑信息来中继从源节点发送的分组。
