Fuzzy Logic Based Mobility Management for 4G Heterogeneous Networks.

Next-generation wireless networks will provide information transmission in Heterogeneous Wireless Networks. It not only offers a variety of wireless access services for integrating different wireless networks, but also takes into account the high bit rate, the QoS management, and the friendly mobility. In this article, the scheme of choosing the suitable network with the best service for a mobile terminal in a heterogeneous wireless network is studied. A new scheme based on fuzzy logic is proposed to employ the important traffic criteria, including bandwidth, dropping rate, blocking rate, signal, and velocity. Finally, the simulation is used to investigate the performance of proposed schemes. The simulation results show that the proposed schemes have better performance than conventional schemes.
