Research Abstract

In cellular systems, many cells are deployed and the service area is covered with these cells. A base station is located at the center of each cell. Mobile stations in a cell always communicate with other stations via base stations. Today's mobile communication systems employ the cellular system. Because the location of base stations of cellular systems is fixed, structure of cellular systems does not change. On the other hand, if base stations can move and mobile stations can be relay terminals, a new communication style is realized.
The purpose of this project is to do fundamental research on mobile information systems with dynamically variable structure. We have considered about (1) Network architecture, (2) Network control, and (3) Network structure. We have obtained the following results.
(1) We have proposed a system which enables mobile terminals to relay information.
(2) We have proposed new routing algorithms and scheduling algorithms.
(3) We have analyzed clustering algorithms, and we have shown difference between these algorithms.
These results are fundamental technology for realizing mobile information systems with dynamically variable structure. Our future problems are to consider new services and applications of mobile information systems with dynamically variable structure.
