多总线接口无线传感器网络节点

Multiple-bus-interface wireless sensor network node

为了实现异构无线传感器网络节点之间的互联通信,从总线设计的角度,提出一种多总线接口无线传感器网络节点的设计方案,以通用高速的USB和ethernet总线作为接口,在传感器节点上灵活挂载多种射频模块等设备,并配置相应的软件协议栈,实现软硬件即插即用的可异构化节点.以USB 2.0总线为例,将蓝牙通信模块挂载到传感器节点的母板模块,将传感器节点异构为具有蓝牙通信接口的无线传感器网络节点.设计结果表明:多总线接口无线传感器网络节点的通信速率不受总线速率制约,扩展性强于普通节点,便于实现支持异构的传感器节点和功能强大的传感器节点.

In order to implement the inter-communication between heterogeneous nodes of wireless sensor networks,the design of multiple-bus-interface wireless sensor network node was proposed in term of bus design.The general high-speed buses of USB(universal serial bus) and Ethernet were adopted to integrate multiple radio-frequency modules or other devices with wireless sensor network nodes.With the attachment of corresponding protocol stack,the heterogeneous node supporting PnP(plug and play) function of software a...
