    • A method for selecting and configuring network supernodes including the following operational steps: in a first set period T1, each node other than the control node in a network sends information on interactions between the node and other nodes to the control node regularly; and in a second set period T2, the control node divides the nodes into a plurality of node clusters according to the received information on interactions among the nodes, and selects supernodes from each node cluster, each node belonging uniquely to a node cluster. The supernode selection according to the invention takes into account both performance and resource conditions of itself and interactions with other nodes. Therefore, when implementing control over other nodes in the node cluster to which it belongs, the selected supernode can find the corresponding node in a short time and shorten the searching time and path, thereby improving the working efficiency. Meanwhile, parameters such as the acquiring period of node interaction information, and the division and adjustment periods of node clusters can be adjusted dynamically with the actual interaction conditions of the network.
    • 一种用于选择和配置网络超节点的方法,包括以下操作步骤:在第一设定周期T1中,除了网络中的控制节点之外的每个节点向节点定期向控制节点发送关于节点与其他节点之间的交互的信息; 并且在第二设定周期T2中,控制节点根据接收到的关于节点之间的交互的信息将节点划分为多个节点簇,并且从每个节点簇选择每个节点的节点簇唯一的节点。 根据本发明的超级节点选择考虑了自身的性能和资源状况以及与其他节点的交互。 因此,当对其所属的节点集群中的其他节点实施控制时,所选择的超节点可以在短时间内找到相应的节点,缩短搜索时间和路径,从而提高工作效率。 同时,可以根据网络的实际交互条件动态调整节点交互信息采集周期等参数,节点集群划分和调整周期。
