Abstract
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.
