Recent Advances in the Internet of Things: Multiple Perspectives

In this paper, we categorize and summarize recent advances in the Internet of Things (IoT) to complement existing IoT survey papers that have not covered its very latest developments. We do this from the three perspectives: information fusion in the IoT, service-oriented IoT, and cloud-centric IoT. These three aspects are largely missing in current literature. This survey contributes to better understanding of the challenges posed by the existing IoT and its likely future developments. The IoT is in the early stages of development. Challenges for future development include network scalability, a continuously produced data stream, and methods for handling heterogeneous data. This review provides insight regarding the three aforementioned aspects. In addition, we briefly summarize the existing literature with explicit references to the corresponding survey papers, thus, providing a panoramic view of the IoT without repeating what is already available in the literature.
