In networked signal processing systems, network nodes that perform embedded processing on sensory inputs and other data interact across wired or wireless communication networks. In such applications, the processing on individual network nodes can be described in terms of dataflow graphs. Through a novel integration of tools for network and dataflow graph simulation, the authors' NT-SIM environment allows comprehensive simulation and analysis of networked signal processing systems. They present a paper that concretely demonstrates the utility of NT-SIM in the context of a heterogeneous signal processing system design.
