Performance Analysis of Economic Model and Radio Resource Management in Heterogeneous Wireless Networks[

摘要

Radio resource management (RRM) is the system level control of co-channel interference and other radio transmission characteristics in wireless communication systems. In this paper we first analyze a utility function based access selection (UFAS) method. Then we investigate a radio resource management and network selection scheme in heterogeneous wireless network. We propose an economic model to allocate radio resources for Code Division Multiple Access (CDMA) Networks and Wireless local Area (WLAN) networks. Moreover we formulate and solve the optimization problem in WLAN and CDMA networks and simulate those equations using MATLAB. Simulated results show that the proposed scheme can achieve more number of users and more social welfare which outperform the utility function based access selection method
