Abstract

The Internet of Things (IoT) has shown unprecedented data generation and connectivity through disruptive applications across various domains. This data, referred to as Big Data, contains valuable information about various aspects of our lives and the physical world. As the IoT ecosystem continues to expand, ensuring the quality of the vast volumes of data it produces has become crucial. Therefore Big Data quality assessment is important in the IoT era to ensure that the data collected and analyzed is accurate, trustworthy, and usable. By performing Big Data quality assessments, organizations can make better decisions, improve their operations, and gain a competitive advantage. This chapter aims to enhance data quality assessment in IoT by providing an overview of its state-of-the-art. Big Data and IoT data properties and their new lifecycles are discussed. Moreover, selected works from the literature on IoT data quality are exhaustively reviewed. Additionally, a holistic architecture of IoT quality management model is proposed capturing key characteristics of IoT applications. Finally, open challenges and possible future research directions are discussed.
