Query´s Reply Generating from Sensors Regarding the Consumer´s Constraints. Application Using MAS

We describe how to generate a reply to a consumer´s query by taking in mind not only the needed information request but also the query constraints. The use of directory facilitator helps the consumer´s interpreter locating an interface able to answer its demand and so, the supplier services that meet its needs. This interface by using a proxy cache is able, regarding the consumer constraints, to generate information replies to requests from earlier data acquisitions. Applying multi-agents system helps creating an effective consumer-supplier´s interface with information treatments and data fusion processes. In this paper, we suppose software architecture and we show by an implementation how agents can handle and treat consumer requirements.
