Adaptive network access mechanism for multi-interfaced terminal over heterogeneous wireless networks

This paper proposes adaptive network access mechanism to support multi-interfaced terminal over heterogeneous wireless networks. Mobile devices equipped with multi mode interfaces perform an access request based on information of available access networks with cost function. The proposed cost function adopts the minimum required bandwidth and signal to interference plus noise ratio (SINR). In order to evaluate the performance, we compare the proposed algorithm against traditional algorithms. Simulation results show that the proposed algorithm improves the blocking probability and throughput.
