Abstract
We provide an architecture for future wireless information services as a collection of autonomous cells which offer information services of widely varying geographic scope. Each MSS (Mobile Support Station) has the freedom to decide how to allocate different information services to its bandwidth and in which form to offer them. Two basic forms of delivery of information service are identified: periodic publishing mode on a publication subchannel and on-demand mode on the on-demand subchannel. We describe, how each MSS makes the decision about which form of service delivery to use and how to structure its publication subchannel by varying the frequency of publication of individual data items depending on the frequency of requests. In this way, we improve the packet efficiency and power efficiency of the client-server protocols by maximizing the number of queries per Hz and queries per Watt. Each mobile client has to be able to interoperate in this environment. This is assured by making cells self-explanatory about their service allocation. We describe how the presented concepts can be implemented by proposing an extension of WWW protocol, called adaptive WWW. We also show how to implement the proposed protocol along the lines of CDPD.
