Architectural standards for internet of things: standardising IoT architecture

Internet of things (IoT) employs un-abatable number of intelligent sensing and actuating devices with advanced software stacks to integrate physical and digital world. To address issues of heterogeneity, communication, connectivity, data collection mechanisms, security and scalability, each IoT application is based on some architecture describing data flow through the system. Given to continuous evolution of IoT enabling technologies, it is challenging to standardise one concrete architecture. This paper provides the synopsis of the IoT architectures, discusses the architectural reference framework of IoT-A, Industrial IoT reference architecture, WSO2 and CISCO architectural models that minimise the architectural levels of abstraction and describe an architectural model based on present IoT enabling technologies. It discusses a model to evaluate the architectural criteria addressed by the discussed architectures to arrive at an architectural reference model that has the potential to serve as a standard for collective IoT application development.
