This work deals with the choice of the cost-effective hardware required to face the challenges and issues proposed by the new trend in the development of intelligent transportation systems. With this aim, a preliminary WSN architecture is proposed. Several commercially available open-source platforms are compared and the Raspberry Pi stood out as a suitable and viable solution. The sensing layer is designed with two goals. Firstly, accelerometric, temperature and relative humidity sensors were integrated on a dedicated PCB to test if mechanical or environmental stresses during bus rides could be harmful to the device. The monitored physical quantities could be used to improve the quality of service. Then, the rationale and functioning of the management and service layer is presented. The proposed cost-effective WSN node is employed and tested to transmit messages and videos.ELETTRONICOenArticle10.3390/electronics81214832-s2.0-85076980894000506678200109https://www.mdpi.com/2079-9292/8/12/1483ING-INF/01 - ELETTRONICA
