Abstract
According to the WiFi, acoustic or visible light opportunity signals in Wireless Sensor Networks (WSNs), we propose a block Compartmental model based on optimal cluster number (Compartmental Modelling). The block model is a fading model, which reflects the attenuation of the opportunity signal with the propagation distance. In order to reduce the overall energy consumption, the optimal number of clusters is calculated by using the different order of the Taylor series expansion of the block model. Finally, a real experimental platform is established by using mobile phone, wireless access point, sound and light signal to analyze the optimal number of clusters. The experimental data showed that compared with the Exponential model and the logarithmic Log model, the energy consumption of CML decreased by about 6 and 8% respectively. In addition, the energy efficiency of the visible light signal is nearly 12% compared to the WiFi harmonic signal.
