摘　　要：　提出一种分布式无线传感器网络体系结构,阐述了相关理论观点,分析其应用价值与研究现状;以减少传感器对网络的依赖为原则,增强传感器感知能力和感知精度、网络强壮性和容错性,并以传感器低功耗为研究思路;设计了以ARM体系结构32bRISC(ReduceInstructionComputer)微处理器、uC/OS- 嵌入式实时操作系统、轻量级TCP/IP网络协议LwIP(LightweightTCP/IPStack),TR1000无线通信模块为核心的一种基于Internet的分布式微型无线网络传感器.A new architecture of distributed wireless sensor network was briefly advanced, and some theoretic argumentations were introduced, some valuable applications are explained and forecasted. Taking account of application requirements, research thoughts and technical project were raised to decrease sensor＇s dependency on network, buildup perceptive capability, perceptive precision, robustness, fault tolerance and low-power. A distributed networked sensor based on internet was designed, which characters 32 bits RISC micro-controller, ARM configuration, uC/OS-Ⅱ embedding real-time operating system, featherweight TCP/IP network protocol-LwlP and TR1000 wireless corresponding truss.
