A Cognitive Heterogeneous Network Spectrum Resource Allocation Algorithm Based on User Needs Feedback

Abstract

Allocation of spectrum resource is the key for heterogeneous wireless networks. Taking the differences between different types of access networks available channel bandwidth and the communication requirements of users into consideration on the basis of cognitive heterogeneous network spectrum resource allocation algorithm based on graph coloring theory, this paper introduces bandwidth control parameter and proposes a spectrum resource allocation algorithm based on user needs feedback, which improves the utilization and fairness of system spectrum resources.
