Optimizing power consumption in iot based wireless sensor networks using Bluetooth Low Energy

This paper proposes an architecture that uses the ultra-low power Bluetooth Low Energy (BLE) wireless standard and a hybrid topology to reduce power consumption in IOT based wireless sensor networks (IOTWSN). A lot of work has been done in the field of Wireless Sensor Networks (WSN) in recent years. Efforts to make efficient, low cost, scalable and easily deployable WSN have been on going. In order to reduce cost and improve life of a sensor node, it is necessary to optimize battery usage and power consumption. This paper looks at BLE as a potential candidate to reduce power in IOTWSN. BLE based activity detection is also incorporated into the system to avoid power wastage in real-time monitoring. The power consideration of the proposed architecture is compared to existing wireless technologies used in WSN.
