Abstract

The invention discloses a mobile application layer multicast tree construction and recovery method based on node comprehensive performance, comprising the following steps: building a mobile application layer multicast tree based on node comprehensive performance: storing node information in a node information table, An index for evaluating the overall performance of nodes is proposed, so that nodes with higher overall performance try their best to undertake more data forwarding tasks, and build an application-layer multicast tree suitable for mobile network environments; mobile application-layer multicast tree recovery based on hierarchical priority: According to the overall performance of the node, define the hierarchical priority for the child nodes leaving the node, formulate the rules for selecting candidate parent nodes according to the different priority levels, and make the affected nodes resume data transmission by contacting the candidate parent nodes, so as to realize the rapid development of the multicast tree recover. The present invention can effectively reduce the number of expected interruptions and reduce the join time delay when constructing the multicast tree, and can effectively improve the recovery efficiency of nodes and reduce the average recovery time delay when the multicast fails.

Description

technical field [0001] The invention relates to the field of application layer multicast, in particular to a mobile application layer multicast tree construction and recovery method based on node comprehensive performance. Background technique [0002] In recent years, with the rapid development of mobile communication technology and the widespread popularization of mobile terminals, people are increasingly eager to quickly obtain Internet services and information anytime and anywhere. The trend of vigorous development affects the whole social process. [0003] In the context of the rapid development of the mobile Internet, in order to meet the growing needs of mobile users for streaming media network communication, multicast, as a key technology for data distribution, is widely used in streaming media transmission, network video, distance education and online games, etc. In group communication applications. In solving one-to-many or many-to-many communication problems, mu...
