摘　　要：树形变化多播技术利用层的思想进行数据传播,减轻了网络的传输负载,避免了网络阻塞,从而加强了网络的健壮性和稳定性。本文提出了蜂窝广播网络中基于优先级控制的树形变化多播应用,网络根据优先级进行通讯,减少了通讯冲突,提高了数据传输效率。tree - varying multicast exploits hierarchy for data delivery, the multicast trees change very frequently, this distributes and balances the stress in the networks, avoiding congestion, and make the network stable and robust. Tree - varying multicast controls the communication by the linking priority, the parameter SIR of the link decides linking priority. After establishing linking priority, In order to improve the communication efficiency, network should provide link according with SIR as many as possible.
