Development of Vertical Handover (VHO) Protocol Based on MIH (IEEE 802.21 Standard) in UMTS-WIMAX Heterogeneous Network
The wireless industry has rapidly moving from the simple voice and text messaging to next generation of services, devices and applications. Voice, data and multimedia at high reliable speeds have become today's norm and the user's expectations on these services are higher than ever before. So, with increasing demand and popularity of the wireless communication, various mechanisms has been proposed and recently deployed to support data traffic over wireless media. Various device manufacturers are integrating more and more network interface to provide the level of services that the users requires. The network developed after integrating the various wireless technologies is called heterogeneous network.
