Abstract
In this paper we investigate the deployment of so-called Media Points to facilitate the provision of personalized services to mobile users within WLAN hotspots with fragmented coverage. An experimental evaluation was performed on the implemented demonstrator to determine the setup and resume times for a push session. The initial setup time for the considered service scenario, wherein 39.03 Mbytes of user data should be pre-cached, has been measured to be on average 6.3 seconds. After a temporary loss of connectivity, the average session resume time takes 2.8 s. The performance has been found to be primarily effected by three procedures, the WLAN Access Point association, the IP address assignment via DHCP and the data caching. Without modifications to WLAN, some potential performance improvements have been identified, e.g., the session setup and resume times can be decreased by approx. 0.5 s when coordinating the DHCP procedure with the WLAN Access Point association procedure.
