Abstract
Mobile devices are beginning to have multiple wireless interfaces. There is a need for these devices to move freely across different networks and achieve seamless handoff across heterogeneous wireless network. In our simulation we performed handover between Wi-Fi (WLAN) and WiMAX network using link trigger [1] mechanism at Layer2. The trigger generated at Layer2 helps in reducing disconnection during handover latency. Trigger mechanism uses certain signal strength level to generate trigger event. Anticipation of the signal strength level improves packet loss performance for various speed of mobile station. The simulation is done for video traffic with NS- 2 [2] simulator.
