In the last decades, the computer science has evolved unimaginably fast . Those technologies, standards, which were created in the end of the last century, became really useful nowadays. The internet and the user equipments atteched to it became an inevitable part of our life. There are endless possibilities on the internet, so more and more people use it on a regular basis. It is more often, that we have to donwload our e-mails, or watch online videos in public places, where it is impossible to find wired environment. However the incerased traffic is hard to handle, especially that our priority must be to maximize the user experience. In this paper I will show the structure and operation of new generation mobile networks, and I will examine the impact of the distribution of the user generated data on different scheduling algorithms.
In the first part – through describing earlier systems – I will show the process, which led to the creation of the current, modern mobile network. I will point out those main properties, which went through a serious transformation until they reched their current state. After I cleared the basics, I will describe the operation of the current, modern networks. I will do this by considering the actual standards of 3GPP (3rd Generation Partnership Project). After, I will review how we can model the internet traffic and then I will examine the impact of these models in a self-developed simulator.
