中文摘要：

自主式智能传感器是一种高度集成的传感器系统，需要运行特定的协议与外界交换数据，能够大幅度减少应用系统的建立和开发时间．参考IEEE1451系列标准，提出了一种易于理解和实现的轻量级应用层协议AgileSN，具有自动发现、高性能、高可扩展性的特点．描述了AgileSN协议模型和工作过程，对比了与IEEE1451的异同，介绍了一种具体实现的途径，并给出了一个应用实例．

英文摘要：

An autonomous smart transducer is a highly integrated transducer system, needs to run a protocol to exchange data with outer world, can greatly reduce the time needed to setup and develop application systems. With the reference of IEEE 1451 series standards, this paper presents a lightweight application layer protocol-AgileSN, for autonomous smart transducers. It is easy to understand and to implement,and features with automatic finding, high performance and high scalability. This paper further describes the AgileSN model and working process, makes comparisons with IEEE 1451, introduces an implementation, and gives a concrete example.
