摘要: 大型传感器网络是指一种规模巨大的传感器网络,其传感器节点多达上万个(设为”),如果每个传感器的采样率为1ms,每个采样点为24bits,则整个网络产生的数据总流量可高达24nkbps(因为”可达上万,所以流量可达几百Mbps)。如何实现这个巨大网络中传感器节点到基站的高速连续数据流的缓存,是保证整个网络顺利运行的关键所在。采用FPGA和异步FIFO的结合,完美地解决了这个问题。

Abstract: Huge sensor network is a large sensor network in scale. In this system, total sensor nodes can reach up to several ten thousands(suppose the numher is n). If the sample of each sensor node is 1 millisecond, and every sample point has 24 bits, so the total
