The IoT has been implemented in personal devices like smat-watch, smart-band and smartphone. The last years the IoT technology has been extended to homes, but now days the IoT has a development delay for automotive industry. This document exposes four communication technologies to allow vehicles to communicate with smart-homes. In this document, CAN and LIN protocols are explained and tested to validate and understand the functionality and integration of both protocol within a real vehicle. Also, IEEE 802.15.4 stardard is explained and tested to validate the connection and data transmission process between a full functional device and a reduced functional device. Finally, the Tread and CoAP protocols are implemented and tested to validate the connection and data transmission between a border router and end-device in order to test on communication protocol used in smart-homes. Finally the implementation and test results are discussed to explain the limitations and problem that can happen in development process of protocol implementations.Continental AutomotiveConsejo Nacional de Ciencia y TecnologíaITESO, A.
