摘要:

针对异步短波单层可靠多播网络群组管理中临时节点加入或退出时网络处理时延较长的问题，提出了一种分层可靠多播网络群组管理方法。通过设置群首节点来减少该临时节点与网络内部成员的交互次数。理论分析和仿真结果表明，该方法较单层可靠多播网络群组管理方法，具有网络对该临时节点处理时延小、群组管理复杂度低等优点，其应用前景广阔。

Abstract:

A layerednetwork group management of reliable multicast method is prop osed to solve the problem of asynchronous group management of singlelayer reli able multicast network in HF communication when temporary nodes join o r exit . The time of intetactive communication between the temporary nodes and members inside the network is reduced though setting the head node of group. Theoretical analysis and simulation results show that this method is more better than the g roup management of singlelayer reliable multicast network because of the less timedelay for dispose of the temporary nodes and the lower network complexity, and has more extensive application prospect.
