Internet-of-things device set configuration for connection to wireless local area network

Abstract

In this paper, new model of interaction in IoT-infrastructure for the set of devices is investigated. Integration into wireless network based on WiFi-technology, software identification, data exchange, and software upgrade problems have been considered for the end-user product that consists of group of devices. The established solution utilizes assignment of the server and client role to devices in the set. The server deploys temporary network so the user device can access it and enter necessary information about network to connect to. Communication mechanisms within customer's network for device set have been also considered. Using proposed models, customer can control device set, send and receive data (particular case for audio data is considered), update firmware and resources of devices directly from his/her own device via specially designed software. We have used set of ESP8266 boards and NodeMCU firmware to implement and test the developed model. The developed prototype system is able to receive configuration of the user network, receive audio data from client device and play audio. This proof-of-concept system can be further extended for the new functionality.
