Abstract

In this work the transmission of multimedia services through heterogeneous integrated terrestrial-satellite networks is analyzed by means of measurement on a real test-bed including a video on demand (VoD) server, an IEEE802.11 wireless local area network (WLAN) integrated with a wired LAN, and a geostationary Ka-band satellite link in service at the Telecommunication Laboratory at IEIIT-BO/CNR, University of Bologna, Bologna, Italy. At first the WLAN radio link is characterized in terms of the mean received power level for different terminal locations within the Lab. Secondary, MPEG-1 video streams are transmitted with different data-rate from the VoD server to many wireless stations and the traffic, for both the single source and the aggregated traffic, is characterized. An integrated terrestrial-satellite LAN is simulated as an example of utilizationof source characterization. Moreover, the quality of service in terms of the average dropped MPEGframes-to-transmitted frames ratio is measured for different channel conditions, data-rate, and the number of wireless terminals requiring the service.
