Two mechanisms have been proposed independently by IEEE and 3GPP; namely, Media Independent
Handover (MIH) and Access Network Discovery and Selection Function (ANDSF), respectively. These
mechanisms enable a seamless Vertical Handover (VHO) between the different types of technologies
(3GPP and non-3GPP), such as GSM (Global System for Mobile Communication), Wireless Fidelity (Wi-
Fi), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications
System (UMTS) and Long Term Evolution (LTE). In this paper, we overview these mechanisms and show
their components, benefits and drawbacks. Then we present our Imperative Alternative MIH for Vertical
Handover (I AM 4 VHO) approach based on the approaches that have been studied in the literature with
better performance (packet loss and latency), less connection failure (probability of reject sessions), less
complexity and more exhaustive for enhancing VHO heterogeneous wireless networks environment
