Internet of Things Architecture and Applications: A Survey

Abstract

The Internet of Things (IoT) is a novel paradigm which is rapidly gaining ground in the scenario of modern wireless\rtelecommunications among devices associated with Internet. Objectives: The main objective of this paper is to discuss\rthe various architectures of IoT from the RFC perspective and layered approach. It also focuses on applications of IOT in\rvarious areas and analysis of security protocols of IoT for the resource constrained devices. Method/Analysis: In view\rof this, the study is carried out by systematic review of scholarly articles and research papers. Findings: The device can\rcommunicate with each other directly within the same network, through the cloud services or indirectly through some\rgateway application and even through some third party where aggregation and analysis of data can take place. When the\rcloud services are used to communicate, interoperability among the IP and Non-IP based devices is the major concern. In\rcase of layered architecture the number of layers decides the complexity of the architecture. Five layered architecture is the\rideal architecture from the perspective of security as well as compatibility. In all the architectures discussed it is observed\rthat, there is a need to focus more on interoperability and standardization which is essential for the security features.
