Abstract
A spectrum allocation method for a cellular network is presented. The method includes: abstracting a cellular network into an interference pattern using a graph theory-based spectrum distribution model; a network node establishing a stakeholder list to represent whether a spectrum can be shared with other network nodes; by obtaining stakeholder lists from other network nodes, calculating a fairness coefficient and determining a lower bound value for the number of spectrum resources which are used; meanwhile, each network node sending out a value related to the fairness coefficient, thereby enables calculate an upper bound value for the number of resources which can be obtained according to the obtained information, to effectively compete for free resources. Through the method of the invention, a network node can autonomously select spectrum resources, fully and effectively achieve spectrum resource allocation fairness and global network fairness, and increase the system throughput and the edge user throughput.
