Context-aware control and monitoring system with IoT and cloud support

The main goal of the paper is to integrate three emergent technologies (Internet of Things, Cloud Computing and Context awareness) in a multi-layered architecture for developing real-time process control agriculture application. For this, the paper presents original solutions for a Control and Monitoring unit (CMU) which performs real-time control as an entity running on an IoT platform, a Context-aware Control Platform (CaCP) with a three-tier architecture, serving as middleware mechanism for interfacing environmental sensors with IoT and Cloud and a four-level architecture to perform agriculture process control, that includes the CMU and CaCP modules. These solutions are validated by a case study application implemented on an IBM Bluemix IoT platform which performs automatic control of an irrigation system using context aware adaptation of controller parameters in response to environmental changes.
