Recent studies of sensor networks concerning large-scale issues and the diverse nature of real-world context have witnessed the debate on homogeneous and heterogeneous sensor networks recently. In this paper, a fume-diffusion-spotting sensor network is investigated based on heterogeneous sensor collaboration, giving inspiration for a suite of similar event-diffusion-monitoring applications. In our heterogeneous sensor network, the energy consumption and the sensitivity of diffusion spotting are tested, with the results showing notable advantage compared to the homogeneous network. The scalability performance is also considered and verified through experiment.
