Stream processing in IoT: Foundations, state-of-the-art, and future directions

Abstract

The emerging stream-processing paradigm has become an enabling technology that powers the time-critical applications for Internet of Things. It offers the ability to collect, integrate, analyze, and visualize continuous data streams in real time, with a scalable, highly available, and fault-tolerant architecture. This chapter outlines the relationship between stream processing and IoT, provides a discussion on the idea and formal concepts of stream processing, and further categorizes the various use-cases of the stream model into the Data Stream Management and Complex Event Processing domains. We also present a detailed analysis on the characteristics of IoT stream data with a focus on their..
