Research on a Bandwidth Allocation Algorithm in Cognitive Network
Keke Liu · Radio Engineering · 2013
As a new network concept and technique,the importance of cognitive network has been widely approved in recent years.In cognitive network,it is a crucial subject how to make bandwidth allocation dynamically based on user requirements and available bandwidth resources.Based on analysis of weights of different users,this paper proposes an improved weighted Max-Min bandwidth allocation algorithm.The simulation results show that this algorithm can improve user QoS guarantee capability as a whole.
