dc.description.abstractThe escalating growth of multimedia content in Internet of Things (IoT) applications leads to a huge volume of unstructured data being generated. Unstructured Big data has no particular format or structure and can be in any form such as text, audio, images, and video. Furthermore, current IoT systems cannot successfully realize the notion of having ubiquitous connectivity of everything if they are not capable to include 'multimedia things'. In this paper, we address two issues by proposing a new architecture for the Multimedia Internet of Things (MIoT) with Big multimodal computation layer. We first introduce MIoT as a novel paradigm in which smart heterogeneous multimedia things can interact and cooperate with one another and with other things connected to the Internet to facilitate multimedia-based services and applications that are globally available to the users. The MIoT architecture consists of six layers. The computation layer is specially designed for Big multimodal analytics. This layer has four important functional units: Data Centralized Unit, Multimodal Data Aggregation Unit, Multimodal Data Divide & Conquer Computation Unit, and Fusion & Decision Making Unit. A novel and highly scalable technique called the Divide & Conquer Principal Component Analysis (DC-PCA) for feature extraction in the divide and conquer mechanism is proposed to be used together with the Divide & Conquer Linear Discriminant Analysis (DC-LDA) for multimodal Big data analytics. Experiments are conducted to confirm the good performance of these techniques in the functional units of the Divide & Conquer computational mechanisms. The final section of the paper gives application on a camera sensing IoT platform and real-world data analytics on multicore architecture implementations.
