The middleware function [21] is to connect different typologies of programs. This interface is part of the architecture enabling sensor connectivity and application layers. The middleware manages important functionalities, such as collecting and selecting the received data from the IoT devices, by providing access monitoring for applications. The security is mainly performed in the middleware system by [33]:

 User identification.

 Identity management.

 A secure data communication system.

 Secure storage.

 A secure software execution environment.

 Secure contents.

 Security resistance.

The middleware improvement is related to the following specifications:

 Interoperability between devices of different technologies by managing heterogeneous interfaces.

 Managing devices performing load balancing.

 Use of API calls.

 Scalability by supporting the communication between a large number of devices.

 Big data interconnection and big data analytics tools.

 AI algorithm interconnection activating sensor data processing.

 Authentication and implementation of access control improving security and privacy.

 Running algorithms on different cloud services.

 Data extraction and data migration improving innovative DB and big data systems.

Middleware is classified as event based when all the components interact with each other through events, or service oriented when service providers are used for resource management in SOAs, or DB oriented, or application oriented.
