The Decentralized Directory Mechanisms for Heterogeneous Personal Environments

Abstract

While the pervasiveness of wireless technology has provided a major impetus to mobile services,challenges the mobility of mobile services much.The characteristics of personal environments:heterogeneity,short distance between devices,and group mobility,are analyzed,and a decentralized directory storage method is proposed based on them for the autonomous organization of devices.It provides proper group mobility support and saves bandwidth,so that,improves the stability of system in personal environments.
