In this work we estimate the handover trigger condition for a mobile node moving out of a WLAN cell roaming in a heterogeneous network environment by performing vertical handover using an end-to-end handover scheme. Determining the characteristics of the handover latency of the employed handover scheme we estimate the appropriate handover triggering instance so as to maximize the WiFi usage but limit the handover failure. The remaining time within the WiFi cell is determined through successive changes in received signal strength as the mobile node moves out of the WiFi coverage cell.

W pracy określono warunki trigera przełączania (handover) w mobilnym węźle komórki WLAN w środowisku sieci niejednorodnej. Określając opóźnienie przełączania określano sytuację przełączania tak aby maksymalizować użycie sieci WiFi ale ograniczać błąd przełączania.
