The edge computing must have the following features:

• The ability to perform an action on behalf of the I-IoT middleware, either offline or online
• The ability to host custom applications
• The ability to run analytics in standalone mode, offline, in collaboration with the I-IoT middleware, or in collaboration with the middleware of the local headquarters
• The ability to carry out actions or download analytics from the I-IoT middleware
• The ability to send unstructured or a specific set of data to the I-IoT middleware on demand or when triggered by a condition

Looking at the functionalities that the Edge must implement, we can understand that the I-IoT Edge is not a simple device, but requires sophisticated abilities in term of performance, management, and computation.
