Abstract
The Media Point concept aims to facilitate the provision of personalized services to mobile users within WLAN hotspots. In this paper we describe our prototypical implementation of a Media Point network. An insight into our performance evaluation using the prototype is given. Our work has shown that the Media Point system functionalities can already be realized and demonstrated using state-of-the-art technologies. Based on our experience the system performance strongly depends on the level of interworking between the various software modules, e.g., SIP modules, DHCP modules, WLAN device driver, etc. In particular the signalling mechanism within the network by means of SIP doesn’t cause any significant delay. Given that the dwell time of the mobile user within the hotspots is in scope of minutes or longer the overall system performance regarding session setup time of 6.3 seconds, wherein 39.03 Mbytes of user data should be pre-cached, and session resume time of 2.8 seconds is found as acceptable.
