Minimising Energy Consumption in WSN-IoT Networks by Focusing on Quality of Service

Abstract

IoT networks are low-powered networks and resource allocation and efficient utilization are critical concerns. Network resources are allocated to the intermediate nodes to perform the various operations (sense, transmit, re-transmit, data aggregation, etc.). These operations are managed by the different layers (M.A.C., routing and PHY). Each layer consumes resources W.R.T. their operations and there is a need to manage the resource consumption W.R.T. the individual layer. Due to bit error rate and signal-to-noise ratio factors, the transmission of the network may be degraded and there is a need to ensure the transmission quality under these constraints. In this study, an energy-efficient scheme for IoT networks will be proposed to resolve the discussed factors and its performance will be analyzed with LoRaWAN/SigFox using various Qos parameters (throughput, residual energy, bit error rate etc.).
