«Invited Lecture» Position information utilization to mobile / ubiquitous communication-system design

Abstract

Ubiquitous environment, where people can use communication resources everywhere, is expected to bring novel communication services. Position information of communication nodes plays important role, at the design of such ubiquitous communication systems. From position information, we can make graphical expressions, namely images. T, relation between ubiquitous communication-design architecture and image-related architecture are broadly compared, using following examples. (1) application of ubiquitous/wireless communication resources, (2) traffic analysis of cellular systems, utilizing probability density function of communication nodes, (3) capacity analysis of Ad Hoc networks, utilizing probability density function of communication nodes, (4) topology control of mobile communication networks.
