摘要: Conflict free spectrum allocation for secondary users in cognitive networks is a challenging problem, since the accessible shared among users. The problem becomes to be especially difficult when it wanted get maximum utility of system considering access fairness In this paper, novel method using bipartite graph matching proposed approach target, where cooperatively optimize maximal while avoiding interference with its neighbors. An idealized centralized presented; experimental results show that algorithm dramatically maximizes utilization together reducing conflictions users, which minimize number starved during allocation.
