Energy-Efficient Data Management With IoT, Fog Computing, and Blockchain

The integration of Internet of Things (IoT), fog computing, and blockchain technologies is revolutionizing data management by addressing critical challenges such as latency, bandwidth, security, and energy efficiency. This chapter explores the synergy between these technologies, emphasizing their potential to optimize data collection, processing, and storage while ensuring sustainability. IoT sensors generate vast volumes of data, which fog computing processes locally to reduce latency and bandwidth usage, enabling real-time decision-making. Blockchain technology enhances data security and transparency, though energy-efficient mechanisms like Proof of Stake and Proof of Authority are essential to mitigate its high energy demands. The chapter examines the strategies for energy-efficient data management, which include smart data collection techniques, selective data handling, dynamic resource allocation, and the use of edge AI for localized processing.
