摘要
LBS系统可对移动终端定位并提供各种与位置相关的业务。但是其信息的迂回查询将导致网络拥塞,严重影响服务质量。而近年来迅速发展的移动Agent可以在异构的网络环境中自由移动,有效地降低分布式计算的网络负载,提高通信效率。文中将移动Agent技术与LBS相结合,实现了查询数据流量的大幅减少和系统效率的提高。
LBS system is mainly used to locate mobile terminates and provide service which concerned with the location. However, when it searches information from data providers, great deals of data is transferred through roundabout mutes, and brings on congestion, and that will reduce the qualiW of the service. While mobile agent, which is developed rapidly in recent years, has an advantage of reducing network burthen and increasing communication efficiency in distributed computing. And this paper gives an LBS system which combine LBS with mobile agent technology, it has quite little data transfer in search process, and as a result, the system efficiency is improved.
