摘要： 目前对传感网的研究主要解决如何在满足特定应用要求的网络指标下，尽可能节约能耗从而延长网络生存期。这些研究假设WSN为一个能够感知真实物理环境的孤立网。然而，实际客户通常处在远离WSN的Internet上，需要一种有效的方式使客户能驱动WSN收集数据并将其快速地传输给客户，因此该文基于对现有研究进行分析总结，提出了一种能够面对多种挑战的传感网与IP网集成方案，采用用户代理、应用代理、注册代理、资源管理器架设WSN与Internet之间的桥梁。通过组件描述和查询操作流程分析，说明了该集成方案较已有框架更加灵活、可靠、能量有效，从而使Internet不同种类的应用能够尽可能快速地获得低成本的WSN查询服务。

Abstract: Wireless sensor network is expected to have a significant impact on the efficiency of military and civil applications. Current works about wireless sensor networks are focusing on providing specific applications. However, there must be an effective way for Internet users to gain access to the data produced by the wireless sensor networks. With WSN becoming pervasive and ubiquitous, it is important to integrate WSNs with Internet efficiently. In this paper, a novel integrated solution is designed and illustrated. The architecture consists of user agent, register agent, application agent, and resource manager. It focuses on providing flexible, reliable, energy-efficient service for various applications.

Key words: Wireless sensor networks, Internet, Energy-efficient, Proxy, Quality of service
