This paper describes a scheme for providing mobile multimedia applications, distributed in a Wireless Local Area Network (WLAN), with seamless communications. Specifically, when multiple WLAN access points are available, the scheme enables a mobile node to select dynamically the access point to connect with, based on a combination of measured parameters such as signal strength, transmission rate, channel load and interference. The proposed scheme has been implemented as part of a cross-layer architecture which offers the possibility of concurrently exploiting multiple networks for the same communication flow generated by some distributed multimedia application. The results which have obtained from an experimental assessment of our scheme demonstrate its adequacy and effectiveness.

Abstract
This paper describes a scheme for providing mobile multimedia applications, distributed in a Wireless Local Area Network (WLAN), with seamless communications. Specifically, when multiple WLAN access points are available, the scheme enables a mobile node to select dynamically the access point to connect with, based on a combination of measured parameters such as signal strength, transmission rate, channel load and interference. The proposed scheme has been implemented as part of a cross-layer architecture which offers the possibility of concurrently exploiting multiple networks for the same communication flow generated by some distributed multimedia application. The results which have obtained from an experimental assessment of our scheme demonstrate its adequacy and effectiveness.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
