Abstract: Research subject. The article provides an overview of types and methods of testing various Internet Things. Method. Existing testing approaches that are used in communication networks nowadays have been analyzed during the research. In this article, set of test specifications was proposed for the complex testing of Internet Things. Core results. During the test it is possible to evaluate various criteria such as probabilistic and time parameters associated with the data exchange between things, as well as with the use of network resources, protocols, etc. Practical relevance. As a validation of the proposed test specifications the natural experiment was made to test the fragment of net- work with the purpose of selecting a standard application protocol for the typical Internet Thing. Protocol selection is based on the determination of the average response time to a request (RTT) using such protocols as MQTT, CoAP and HTTP.

Keywords: Internet Thing, IoT, Wi-Fi, Bluetooth, ZigBee, MQTT, CoAP, HTTP.
