Abstract: 4G network is the most efficient technology today. Its effectiveness in providing very high data rate and supporting various technologies simultaneously is very helpful in this fast developing world. Hence, 4G has emerged out as a highly promising network. This wireless network is capable of supporting a number of technologies and so it is necessary to assure that the mobile terminal is being handed off to the right technology. This decision has to be taken by considering several factors related to the base station, access point and received signal strength. So in this paper, we develop a vertical handoff technique which performs handover only after confirming that the handoff will be valid so as to avoid any false handoff occurrence. Then the decision related to the technology to which the mobile terminal has to be connected is made by using the decision function. Thus, in this paper the mobile terminal is handed over to the right wireless technology without carrying out any false handoff process.
Keywords: 4G network; wireless technology; handoff process; mobility.
