Performance Analysis of Heterogeneous Networks Based on SINR Selection Strategy
Résumé
New integrated wireless and mobile networks are emerging to offer a wide range of services through heterogeneous networks anywhere at any time. The promotion towards these networks requires a user-centric approach which could enable users to control their terminal behavior in an efficient way. Each mobile terminal equipped with heterogeneous interfaces can access different network technologies and perform the corresponding services. In this paper, we consider a network selection strategy based on the estimated Signal to Interference-plus-Noise Ratio (SINR) value in an integrated heterogeneous network. Based on the Markov model, we describe the state of the heterogeneous system at any time, taking into account the quality of service (QoS) requirements of all users communicating in the heterogeneous networks. Then we analyze the system performance in terms of the blocking probabilities and connection quality of calls. Moreover, resource blocks allocation for services with different QoS requirements is also analyzed in this paper.
