WiFi/WiMAX seamless convergence with adaptive vertical handover for continuity of Internet access

The next generation of the wireless networks will consist of several overlapping tiers. Provision of undisrupted communication to mobile users is a challenging task. Handover delay is one of the problematic issues that users are faced in the heterogeneous networks. However, in the case of both the W...
