Low Power IoT Network Sensors Optimization for Smart Cities Applications

Nowadays, Low Power Wide Area Networks (LPWAN) assumes an important role on the evolution and growing of wireless network sensors. The actual technologies based on Internet of Things (IoT) allow sensor connectivity to Internet. This feature enables real time acquisition of several physical data important for smart cities monitoring. Depending on the adopted wireless communication standard, sensor information is transmitted according to several radio communication conditions, namely binary rate, bandwidth and duty cycle policy. This paper presents a wireless sensor network design based on power consumption optimization. The proposed optimization focus on the number of end devices (sensors), distance of each end device to the gateway and the radio configuration parameters. Two end devices distribution around the gateway are analyzed for prior network power consumption optimization. The obtained results are supported on two different IoT devices.
