异构个人域网络中的分布式目录信息存储

The Decentralized Directory Mechanisms for Heterogeneous Personal Environments

移动技术和泛在计算的融合在推动移动业务发展的同时也带来了移动性方面的挑战。分析了移动泛在条件下个人域网络的异构性、短距离性与组移动性的特征,针对这些特征给出了一种无中心化目录存储机制,用于个人域网络的自主维护与组织。在大量设备成组加入的情况下,消耗的带宽资源不会随之大幅增加,有效节约了带宽,维护了系统工作的稳定性。

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.
