Abstract

Because of the limited bandwidth, wireless communication in mobile environments is much more expensive than the communication cost in wired network. Thus, to save the cost of wireless communication, during the process of wireless Web page access, mobile unit usually prefetches some Web pages into its local cache and then disconnect itself from the network, so that updates are performed in its local cache and propagated back to Web server upon reconnection again. In this paper, after discussing the design rationale of a new Web page access mechanism, the performance of this mechanism is analyzed theoretically and experimentally. The results show that the efficiency of update propagation is improved and the burden of Web server is decreased.
