摘　　要：简单组播转发协议在没有接收者时,组播源也会洪泛整个网络,这样就会产生不必要的重复数据.为了避免在移动自组网中出现这种问题,作者针对简单组播转发协议提出了一种扩展方法,即根据有限的洪泛范围和到达所有组播接收者的单播,对组播源列表中的每个接收者计算一个混合值.以这个混合值为标准选择有限的洪泛方式与单播方式的最佳组合来最小化洪泛带来的网络开销.Simple multicast forwarding protocol in the absence of the recipient, the multicast source will oe tloooeo throughout the network, this will lead to unnecessary duplication of data. In order to avoid MANET this problem, the authors propose protocols for multicast forwarding simply an extended method, which based on limited flooding scope and reach all the multicast receivers unicast, multicast source list calculated for each recipient a mix value. With this mix is the standard way with limited options flooding the best combination of unicast to minimize network overhead caused by flooding.
