Adaptive Resource Allocation Mechanism for Broadband Mobile Network
Mobile networks have been continuously developed from 3.5G to 3.9G/4G with high speed wireless technologies (i.e., broadband mobile network). So, mobile networks need to provide more sufficient QoS mechanism to provide enhanced user's satisfaction. In this paper, the authors propose a new adaptive resource allocation mechanism based on utility function borrowed from the field of microeconomics. Through the simulation and calculation evaluation, they show that adaptive resource allocation based on user preferences is effective. Currently mobile networks are being evolved from 3.5G to 3.9G/4G, which is broadband mobile network, integrated into IP core network based on IMS (IP Multimedia Subsystem).
