The invention discloses a construction and recovery method of a mobile application layer multicast tree based on node comprehensive performance. The construction and recovery method of the mobile application layer multicast tree based on the node comprehensive performance comprises the following steps: the construction of the mobile application layer multicast tree based on the node comprehensiveperformance: storing the node information in a node information table; providing indexes for evaluating the comprehensive performance of the node; making the nodes with high comprehensive performancetry to undertake more data forwarding tasks; and building the application layer multicast tree applied to a mobile network environment. The mobile application layer multicast tree recovery based on ahierarchical priority: defining the hierarchical priority for a child node leaving the node based on the comprehensive performance of the node; formulating rules for selecting candidate parent nodes based on the different hierarchical priorities; and restoring the data transmission of the affected node by contacting the candidate parent node to realize the fast recovery of the multicast tree. Theinvention can effectively reduce the number of the expected interruptions and reduce the adding time delay when constructing the multicast tree; and when the multicast fails, the recovery efficiency of the nodes can be improved, and the average recovery time delay can be reduced.
