普适计算中间件技术的研究与进展

当前，普适计算已经成为计算机科学中一个极具活力和影响力的研究领域。普适计算环境规模很大并且具有高度异构性，如网络架构的异构性、硬件平台的异构性、操作系统的异构性、应用服务的异构性等，而普适计算中间件技术可以解决异构性和跨平台特征，提供不同服务的集成应用，因此成为普适计算中的一个研究热点。基于此，本文对于目前国外关于普适计算中间件技术的研究现状做了一个总结；通过分析和比较，给出了普适计算中间件的设计原则；探讨了普适计算中间件技术的未来发展方向。

Research and Development of Pervasive Computing Middleware Technology

Pervasive computing has become one of the most effective fields in computer science. In pervasive computing environments, it has very large scale and high heterogeneity, which exists between network infrastructures, hardware platforms, operating systems and application services. Since pervasive computing middleware technology is capable of solving the problem of heterogeneity very well, it has become a hot spot in pervasive computing. The existing related researches on pervasive computing middleware are analyzed and compared in the paper, and the design guidelines for pervasive computing middleware are presented, too. At last, a summary and a prospect are proposed.
