    • Provided is a resource allocation method performed in a wireless network formed of a plurality of nodes, the resource allocation method including the operations of forming clusters and electing cluster heads respectively for the clusters; determining whether a node from among the plurality of nodes forming the wireless network is an edge node; if the node is not the edge node according to a result of the determining, collecting link information related to other nodes in a cluster that comprises the node, and delivering the link information to a cluster head of the cluster; and if the node is the edge node according to a result of the determining, otherwise, obtaining link information and scheduling information from an edge node of another cluster within a communication range with the cluster comprising the edge node, and delivering the link information and scheduling information to the cluster head. The resource allocation method decentralizes a load of calculations to several nodes, wherein the load may be centralized to one node in a large ad-hoc network, so that an energy efficiency of the node may be increased, and since the several nodes sequentially perform simple calculation, a total of the resource allocation time may be reduced.
    • 提供了一种在由多个节点形成的无线网络中执行的资源分配方法,所述资源分配方法包括分别形成簇并分别为簇选择簇头的操作; 确定来自形成无线网络的多个节点中的节点是否是边缘节点; 如果所述节点根据确定结果不是所述边缘节点,则收集与包括所述节点的集群中的其他节点相关的链路信息,并将所述链路信息传递到所述集群的集群头; 如果所述节点是根据所述确定结果的所述边缘节点,否则,从与所述边缘节点的所述群集的通信范围内的另一群集的边缘节点获取链接信息和调度信息,并且传递所述链接信息和调度 信息到簇头。 资源分配方法将计算负载分散到若干节点,其中负载可以集中到大型自组织网络中的一个节点,使得节点的能量效率可以增加,并且由于几个节点顺序执行简单 计算时,总共可以减少资源分配时间。
