IoT Middleware Model for Time Sensitive Data: A Survey and Framework

Abstract

Software like Internet of Things middleware will always indulge as an interface between components of the IoT, initially any components had not been designed to be connected with each other and will provide many services and functionalities that enable the integration, interoperability, and management of varied IoT devices, platforms, and applications. IoT platforms are also referred as IoT middleware. Communication middleware is the one component of IoT middleware and provide protocols and standard for data exchange. The enormous volume of information/data generated by IoT devices cannot be managed without IoT middleware. Various types of facts can be retrieved from IoT devices and time sensitive data is one of the very important type of data that needs to analysed keenly due to its versatile importance. In time-sensitive applications, perception of timing adopts another feather. The connected network has to assure bounded latency and jitter, along with real-time behaviour, well-defined as the capability to distribute the valuable data earlier a given timestamp, referred as deadline. As per metrological perspective every data essentially be sent before a given timestamp. Handling time-sensitive and exact dimensions is highly important and safety-critical applications can be easily managed.
