全分布式位置管理策略的负载和位置更新性能研究

摘要

The fully distributed location management strategies, as well as their distributed database (DDB)architectures, are quite different from traditional location management strategy and its HLR-VLR structure. This paper presents a new methodology for evaluating database load and performance of location updating in different hierarchical DDB architectures,based upon the probability dense function about users'mobility pattern%分布式位置管理策略及其分布式数据库结构与传统位置管理策略和HLR-VLR结构有显著区别。本文基于一种对DDB结构新的性能估计方法，从用户的移动性概率分布出发，对DDB结构下的数据库负载和位置更新性能进行了研究。
