Abstract

A mobile information announcement system has been constructed. In the system, a mobile computer can announce information at any place and any time. Moreover, the bandwidth problem between a mobile computer and an access point is pointed out. If the bandwidth of the network is narrow, all requests from clients cannot be processed by a mobile computer. An announcement mechanism for a mobile computer, which can effectively announce information with a narrow bandwidth network, is proposed. In this paper, in order to optimize performance of the proposed mechanism, parameters of the mechanism are analyzed in two kinds of networks through experiments. By optimizing parameters, the performance of the mechanism improves about 40%on wireless LAN compared with the performance without consideration of jitters in communication.
