Abstract
This thesis focuses on the growing area of the Internet of Things (IoT), where various devices and sensors, parts of electro-mechanical controllers, automation systems and many others, are usually interconnected wirelessly. This research has three basic parts:
• Wireless communications on Wireless Sensor Networks (WSN)
• Distributed processing on Wireless Sensor Networks
• Decision making according to proper data processing
Wireless communications between sensor networks is a sector that is continuously being developed, requiring new techniques and protocols for successful communications. The analysis and study of already existing protocols is a major issue for the community of the Internet of Things. This is the first objective of this thesis, that has a target to find the most efficient architectures of interconnection of Wireless Sensor Networks, networks of automatic controllers and electro-mechanical parts and other applications and effective management of their data. Communication models and the design of implementation of these entities will be considered in the light of best performance.
The second challenge is the distributed processing in distributed systems (microprocessors, mobile devices, etc.) which is the reverse of the accumulation of all functions and data that promotes the logic of today, with the field of Cloud Computing. Since the data processing and the sharing of processing power in different systems is another area with little research, this challenge will also be covered in this thesis, which makes it a very interesting research aspect.
The third area of research is the adequate analysis of collected data for decision support. Data analysis can be done either at the device level or at the level of IoT infrastructure (eg fog computing, cloud computing). Indicative target areas of the research thesis, are applications in areas just as Medical and home automation applications.
Subject of study
This thesis examines and analyzes all relevant communication technologies, different platforms, operating support systems and various programming environments that take place in the environment of Wireless Sensor Networks and FOG Computing.
It focuses on the evaluation of communication protocols between sensors through simulations and experiments on real platforms and in the evaluation of distributed processing techniques of the FOG Computing sector.
Distributed applications and lab tests will be made, in order to analyze and study the performance and draw conclusions, regarding the results of the evaluation of the applications and the selected metrics of performance.
