普及计算服务发现技术

A Survey of Service Discovery Technique in Pervasive Computing

普及计算作为分布计算一个新的发展方向 ,受到学术界和工业界越来越强烈的关注。服务发现技术是普及计算领域中的一项基本技术。介绍了服务发现相关概念和系统模型 ,讨论了七个有代表性的服务发现系统 ,并且分析了服务发现系统的关键技术和当前研究工作中所面临的挑战。

Pervasive computing, as the evolution of distributed computing, is receiving more and more attention from both academia and industry. Service Discovery is one of fundamental techniques of pervasive computing. This paper first introduces some concepts and model of service discovery system. It then discusses 7 representative service discovery systems. Next, it analyses some key techniques of service discovery. The paper closes with a discussion of some research challenges of current systems.
