Performance Analysis of Vertical Handover between

For the development of the 4G wireless networks the design of seamless and efficient Vertical handovers is an essential issue. Next generation wireless communications will likely rely on integrated networks consisting of multiple wireless technologies. So the integration of WiMAX with other wireless technologies, such as WLAN, Wi-Fi, UMTS or 3G, has attracted research community for the last few years. With the recent introduction of mobility management frameworks in the IEEE 802.16e standard, the performance largely depends on the capability of performing fast and seamless handover between heterogeneous networks. Seamless vertical handover between different access technologies is a great challenge as it needs to obey different performance constraints. This research work aims to analyze performance of vertical handover between different access technologies in terms of low packet loss and minimum latency.
