| 摘 要： | 针对延迟容忍网络中的组播路由问题，提出了一种基于委托转发技术的组播路由算法。该算法是在详细分析组播路由设计需求的基础上，结合延迟容忍网络中节点移动特性，对委托转发技术中节点属性值和节点对转发标准进行重新设计。其节点属性值是面向组播会话的，节点对转发标准是动态适应网络状态的。仿真结果表明，相比于其他基于复制方式的组播路由算法，该算法具有更好的性能，尤其是在对网络开销的控制方面，因此，更适用于延迟容忍网络。

| Abstract: | For the multicast routing problem in delay tolerant networks,this paper proposed a multicast routing algorithm based on delegation forwarding method,and analyzed the requirements for designing multicast routing strategy in detail.Combining with nodes' mobility characteristics,the proposed algorithm redesigned the node's quality and the forwarding criterion between nodes for delegation forwarding method.The node's quality was corresponding to multicast session and the forwarding criterion between nodes was a... |
