Investigation of methods for remote control IoT-devices based on cloud platforms and different interaction protocols

Internet of Things (IoT) is a concept of communications between multiple devices equipped with sensors and actuators for the purpose of convenience and economic benefits. In connection with the rapid development of IoT concept it becomes necessary to use those or other instruments for the control and management of IoT. Considered scenario is based on the interaction between the central element (smart home gateway), which ensures the connection of various sensors and actuators within a smart home. Management is carried out on the basis of specialized application. In this paper as a gateway uses single board computer Raspberry Pi 3 and the sensors and actuators communicate with the gateway using BLE — technology. We consider the operation of applications for remote management of the actuators and sensors using a proper framework AllJoyn. In conducting the study focuses on components of the framework AllJoyn: HTTP protocol, which is the most common in data exchange between smart home gateway and remote applications, MQTT protocol. During the testing of HTTP and MQTT protocols, realized as AllJoyn at the gateway threshold levels of operation have been received. Thus, the paper presents the results of complex testing fragment smart home network, the basic communication protocols and thresholds obtained their operation in conditions of high functional load.
