A Comprehensive Survey on Role of Fog Computing and Need for Semantic Technology in Modern Computing Platform

Fog computing can be considered as one of the trending paradigms, as it has the potential of bringing the end devices closer to the cloud. Fog plays a vital role in bridging the gap between the end user and cloud with low latency, which in turn helps in the better realization of Intelligent IoT. The emergence of IoT applications has paved the way for Semantic Interoperability (SI). Instead of storing raw data, SI attempts to annotate these data with semantic information that ensures smart management of huge volumes of data generated by IoT. Nevertheless, such semantic reasoning in the cloud can be computationally expensive as it deals with enormous amount of incoming data. So, distributing the procedure of semantic reasoning among a hierarchy of distributed fog nodes than in a centralized cloud will gives the better result. This research study investigates how semantics work in fog computing
