一种基于效用理论的异构接入网选择机制

he development of a variety of wireless access technologies will provide users richer network resources. However, it also makes the wireless network environment becomes more complex in the futrue. To make full use of network resources and keep user terminals always best connected, an effective access network selection mechanism is the key issue. Based on utility theory, an access network selection mechanism is proposed to provide the best network selection for each user application. Simulation results indicate that this mechanism can make full use of network resources while reducing energy consumption and monetary costs.
