Design of node with SOPC in the wireless sensor network

A wireless sensor network has been widely used but its real-time data processing capability is still limited. This paper proposes a novel wireless sensor network node design based on SOPC (System on a Programmable Chip). In our design we adopt two schemes in FPGA development board: It can be either embedded a single processor, various necessary IP core and custom IP core with FSL (Fast Simplex Link) in it; or a dual processor and relative IP core according to our actual needs. If necessary, a μCLinux operating system can also be embedded on it. The design makes full use of the superiority of SOPC in real-time data processing and it completes a better node design. © 2010 ICIC International.
