Research and Development of Service Discovery Problem in Pervasive Computing Environments
普适计算环境下服务发现问题的研究与进展

In pervasive computing environments,the structure,composition,resources and services always change whereas service discovery technology can find and locate the requested services and provide a better resolution to in- tegrate various resources in pervasive computing environments.Because of this,service discovery problem becomes a hot spot and an important field in pervasive computing research.The existing service discovery protocols are analyzed and compared in the paper,and at last a summary and a prospect are proposed.
