摘要
In this work, an analysis of the physical radio channel propagation for the deployment of a wireless sensor network for intelligent street lighting is presented based on an in house implemented deterministic 3D ray launching code. Simulation as well as measurement results from a deployed wireless sensor network, based on ZigBee motes for an intelligent street light control system confirm the topological and morphological dependence of the considered scenario, given to diffraction and scattering from the street lights in which the sensor are located. Received power levels as well as performance metrics given by Packet Error Ratio values are presented in order to validate radioplanning estimations. The results can be applied to the optimal radioplanning of the wireless systems prior to deployment phase, in order to achieve maximum system performance while minimizing power consumption.
