Abstract

This paper proposes the new architecture of information delivering system that can support a life and an activity of people at the area crowded with many visitors, residents and office workers in metropolitan areas and addresses simple infrared broadcasting protocol IrBRC and IrUCIS. Proposed architecture has two-hierarchical-server structure to reduce loads that are concentrating on server when there has many accesses at the same time. Consistency against frequent update of information on hierarchical severs is kept by managing their version. Classifying distributed information into two groups such as "content to show" and "content to go" makes it possible for receiver to carry retrieved information with his/her mobile terminal, and that creates information distributing flows from creator to receiver. Implemented simple infrared broadcasting clears congestion issue caused by many receivers' multiple accesses for retrieving.
