| 摘 要： | 基于按需多播路由协议(ODMRP)，提出一种改进的可靠多播路由协议。该协议采用集中报错机制，在尽量不增加控制分组数目的前提下，将一定数量的数据分组丢失事件集中在一个聚合的NACK中，并将该NACK添加到Join Table分组中，通过上游节点重传实现ODMRP协议的可靠传输。在OPNET下进行仿真实验，结果表明，与原协议相比，改进协议的数据包投递率提高了2.5%。

| Abstract: | An improved reliable multicast routing protocol is presented based on On-demand Multicast Routing Protocol(ODMRP).The protocol using NACK aggregation is to contain number of control group as precondition.The loss events of data packet in amount are centralized in an aggregated NACK.The aggregated NACK is added into Join Table group to realize the retransmission by father node to get reliable ODMRP communication.Simulation result shows that the packet delivery ratio of the improved protocol enhances mostly u... |
