| 摘 要： | 为提高应用层组播的性能,提出基于节点综合性能的总线型应用层组播模型(CPBM),CPBM通过引入分层结构和节点综合性能的概念,采用基于节点综合性能的动态规划方法使系统能随时间的变化自动调整各节点的位置,在每个域中,节点按照综合性能由高到低的顺序依次连成总线型域,综合性能最高的节点作为Leader 节点.仿真实验结果表明:与传统的NICE 模型相比,该模型具有更高的数据传输率和带宽利用率,在一定程度上提高了应用层组播的性能.

| Abstract: | In order to improve the performance of Application Layer Multicast (ALM), bus-type model based on comprehensive performance for application layer multicast ( CPBM) was proposed, which introduced both hierarchy architecture and the comprehensive performance of node. Dynamic programming method based on the comprehensive performance of node was used in CPBM, so that the system could adjust the location of each node automatically according to its comprehensive performance. Besides, in every cluster, the nodes followed into a bus-type with their comprehensive performance from high to low, and the node with highest comprehensive performance was selected as the Leader node. Simulation results show that CPBM possesses higher data delivery ratio and bandwidth usage compared with NICE, so that it can improve the performance of application layer multicast fairly well to some extent. |
