Middleware for Internet of Things: A Study

Abstract

The significant progress in smart devices has lead to the shifting of actual Internet to the Internet of Things (IoT). Internet of Things is invading our real lives. In this new Internet vision, trillions of smart dynamic objects and areas will be connected to the Internet and interact between each others to achieve common applications. This new Internet vision requires suitable IoT infrastructure that offers the main Internet of Things functionalities to facilitate the development of IoT applications. Middleware is the software layer between technological and application layers. It is mainly used to afford common services and functions to applications and to abstract implementation details to ease more complex application development. In this paper, we review the main challenges facing Internet of Things middleware and survey the most well known middleware that have been proposed in this field.
