Summary:
Nowadays the technology is evolving rapidly, many manufacturers are launching smart mobile devices on the market which are creating increasingly demanding users. This results in a trend of increasing the volume of data traffic transferred in the communication networks and in conjunction with the Internet of Thing, a heavy congestion is created on the network, which creates long delays and finally has significant impact on users’ experience. Therefore, it is necessary to develop a new generation of communications networks, fifth generation (5G), to meet the increasing users need, having as their main objective the achievement of the minimum latency and the maximum throughput. 5G networks will be able to use new technologies such as Cloud computing, using network virtualization technology as well as an even more state-of-the-art technology which is an extension of the Cloud Computing and is called Mobile Edge Computing (MEC). Edge Computing does not replace, but complements the Cloud Computing and has the feature to be close to end users in order to serve their requests quickly, and to reduce the traffic to the core of the network while the quality of service is increased.
This diploma thesis contains four chapters. In the first chapter there is a historical overview of mobile communication networks, followed by an extensive description of the fifth generation mobile communications systems (5G) where is described in detail the evolution reasons of fifth generation of mobile networks, the architecture of 5G systems is described, the dominant technologies that 5G systems will be based on and finally is described some funded research projects that aim to realize the phantom of fifth-generation networks.
In the second chapter is presented a detailed description of Cloud Computing. More specific, primarily the Cloud Computing is defined, its historical overview is presented, its basic features, its advantages and disadvantages are described, the available cloud computing models which are available today is presented, the dominant cloud computing platforms, some security issues resulting from the use of cloud computing technology is mentioned and how Cloud Computing can be used in 5G systems.
In the third chapter there is an extensive description of Mobile Edge Computing technology having analyzed its basic features, its architecture, its advantages and how MEC can be used in 5G systems. Moreover, in this chapter is described a generalized form of MEC which is called Fog Computing and also are presented its basic features, its architecture for 5G systems and some security issues.
Finally, in the fourth chapter is described the Internet of Things (IoT) world, the IoT architecture, all the existing communication models of IoT, and which of the referred platforms can be applied properly in the IoT world is mentioned. Also, is described the IoT properties and features and the number of applications that IoT supports.
