摘　　要：利用P2P思想,在应用层设计一个覆盖网络,网络内部以频道分簇,簇内节点以树形组织。描述了节点间管理协议。在父节点选择算法中,综合考虑了节点间的距离、节点在线时长、负载状况、与根节点的跳数等因素。最后,通过分析对比,说明该系统具有较低的数据传输延迟、较好的稳定性和鲁棒性。An overlay network is designed in the application layer with the notion of P2P. This network divides the cluster with channel, and the peers in a cluster are organized in the shape of tree. The management protocol among the nodes is described. The parent node selection algorithm in this paper takes account of many factors comprehensively such as the distance between the peers, the online time, the load status and the number of jump to root. The analysis and comparison in the end of the paper show that this system has a lower data transmission delay and the better stability and robustness.
