Design and implementation of a device network application for distributed line-crossing recognition

In this paper, we present a complete distributed sensor system design with features of low energy usage and small size. In this system, a distributed application for line-crossing recognition (LCR) is demonstrated as a concrete example. This system includes optimizations associated with algorithm streamlining, communication protocol configuration, and hardware/software implementation. We summarize our developed light-weight distributed algorithm for line-crossing recognition, together with its specific protocol implementation, and present the corresponding hardware implementation. We also describe a system prototype that we have built based on off-the-shelf devices, including a field programmable gate array (FPGA).
