Abstract :
The delay and jitter of an RTP (real time protocol) stream transported by TCP over WLAN are examined as candidates for assisting handover between networks. Jitter was found to be a good indicator of when a mobile is close to the edge of a WLAN cell and was used to spawn a vertical handover mechanism. The implemented handover scheme used an averaged delay difference to complete the handover of the video stream.
