A Review: Vertical Handover between Wi-Fi and WiMAX

Over the past few years, rapid advances in wireless broadband networks have been driving the evolution of communication and network technologies towards next generation omnipresent computing environments. If a mobile station velocity is high and its movement pattern is irregular, unnecessary handovers likely occur more frequently, and then a seamless handover algorithm between heterogeneous wireless networks is required. This paper describes two techniques Wi-Fi (Wireless Fidelity) & WiMAX(Worldwide Interoperability for Microwave Access) used in wireless communication along with their comparison and how vertical handover takes place between these two heterogeneous techniques. Here the heterogeneity is defined in terms of WiMAX and Wi-Fi Networks. The aim of this paper is to study these two techniques and describe the basic vertical handover procedure
