Non-connection Wireless IoT Network Control Using WiFi and Bluetooth Beacon
Sanggon Lee · 2017
In this paper, we propose a control system and algorithm that can send and receive data between smartphone and IoT device without connections. Existing technologies have incurred overhead such as current consumption and network occupation required for connection and connection maintenance for services and products that do not require continuous information reception or control. In order to reduce the overhead of existing technology, this paper proposes a method of transmitting control information by omitting a separate connection process by transmitting a beacon signal to an IoT device when a user inputs a control command. Soft AP and low power Bluetooth (BLE) are used in smartphone of Android platform and evaluated in Home IoT Network environment. As a result of implementing the proposed algorithm and measuring the performance, there is no overhead such as current consumption and network occupation required for connection and connection maintenance occurring in existing technology. The system using Soft AP was controlled at speed equivalent to that of existing technology within 8 meters in terms of control speed and improved about 10% at a distance of 8 meters or more. The system using BLE showed about 30% improvement in overall distance.
