Survey on Seamless Vertical Handover between Wi-Fi and WiMAX Networks Using RSS and Motion Detection

In today’s world network has become as important as basic needs for human being. People may need internet connectivity to do their work even when they are on the go. For such people connectivity to network is very important and they expect uninterrupted services even when they move from one network to another or one place to another. Different wireless internet services are used by different users to connect to internet while they are on the go. In this information crazy world, everyone wants an uninterrupted, and quality of service for him. Different kinds of networks are used for getting connected to internet like Wi-Fi, WiMAX, GSM, etc. User may also wish to use different types of networks simultaneously. So, the process of switching from one network to another networks become important and critical for seamless internet connectivity. In this paper we are discussing implementation strategy for vertical handover between Wi-Fi and WiMAX networks. Wi-Fi provides Local Area Network for users and WiMAX provides broader network to users (MANs), but user expects his network access to be uninterrupted and he even want his session to be continued between this network switches.In this paper we also have considered a RSS and motion detection to decide the appropriate network for better seamless services.
