Comparison of communication protocols for low cost Internet of Things devices

Internet of Things (IoT) uses the connection between devices to improve their efficiency and user experience, being the communication one of the main elements for a proper IoT network. This paper presents a review of the most common wired and wireless communication protocols, discusses their characteristics, advantages and disadvantages as well as a comparison study to choose the best bidirectional sensor network composed by low power devices such as Arduino, ESP-12 and Raspberry Pi.
