PERFORMANCE ANALYSIS OF WiFi/WiMAX VERTICAL HANDOVER BASED ON MEDIA INDEPENDENT HANDOVER

Currently, there are several wireless networks deployed around the world. Examples include cellular networks, metropolitan area networks and wireless local area networks. Given the heterogeneity of the existing network technologies, the diversity of mobile applications, and user requirements, ensuring service continuity for a mobile user when changing different access network becomes a mandatory aspect. The aim of this work is to study and analyse a solution based on the IEEE802.21 standard, to enable interoperability between different networks. The assessment takes place in a context of mobility between WiFi and WiMAX networks. The network simulator NS2 is used during this study.
