Part of the data in the Internet of Things (IoT) will be generated by wireless sensor nodes organized in Wireless Sensor Networks (WSNs). However, these nodes are mainly designed to have low costs, which implies constrained memory and energy supplies, and does not permit high data transfer rates. Despite that, modern applications rely on the knowledge acquired by WSNs to trigger other systems and sensed data has become critical to avoid economic-and living-losses. Therefore, it is important to optimize data transmissions in WSNs to support more wireless sensor nodes and a higher diversity of sensed parameters. The thesis “Prediction-Based Strategies for Reducing Data Transmissions in the IoT” extends a paradigm that exploits WSNs to the utmost: data that can be predicted does not have to be transmitted. We simulated and tested a self-managing WSN architecture in the cloud to adjust the sensor nodes' sampling intervals. For the future generations of WSNs, we designed a theoretical model for estimating the efficiency of prediction-based data reduction methods in WSNs. It will permit a strict control over the quality of the reported data without being harmed by the adoption of a higher number of sensor nodes; hence, collaborating to the IoT's growth.
