- Abstract
- The development of new wireless cellular network technologies is always in progress. As 3G has been considered the foundation of mobile broadband, the latest generation of cellular mobile communications, that is, 5G New Radio, is expected to realize the networked society, where everyone and everything are seamlessly connected everywhere and every time.
To ensure the connectivity and provide the required services, the cellular network could first be simulated, and the performance evaluated. Simulations are made as a method to evaluate the performance of the connectivity and services. In addition, building new network simulators and efficient scheduler algorithms, could be crucial for dimensioning the networks to fulfill the new...

This thesis work includes two main parts. First, a network model that reflects modern cellular architectures and user services, are defined and implemented. Second, a system level simulator that uses different scheduler algorithms is also developed. Several main factors and requirements that have been considered when building this simulator are, scalability, avoiding high computational complexity as much as possible so that the processing time can be reduced, and the simulator can be easily further developed.

- As there is a saying, “All models are wrong; but some are useful” by George E. P. Box, aiming to implement an efficient model that models user’s traffic in modern systems and provisioning them with the actual resource demands, is considered to be very useful.
This Master Thesis has created the fundamental basic parts of the simulation tool such as the flexible traffic model for each user, the definition of the area covered by heterogeneous cells, the positioning of the users in the cell area, a basic radio model to reflect the path loss of the radio signals due to the distance between the transmitter and receiver, and finally the fundamental allocation of the radio resources for the created traffic performed in the scheduler....

This Master Thesis has created the fundamental basic parts of the simulation tool such as the flexible traffic model for each user, the definition of the area covered by heterogeneous cells, the positioning of the users in the cell area, a basic radio model to reflect the path loss of the radio signals due to the distance between the transmitter and receiver, and finally the fundamental allocation of the radio resources for the created traffic performed in the scheduler. Furthermore, the execution time of the simulator have been measured.
The cellular area has been modelled with different number of users, each using different type of services like voice, video streaming, file downloading, web browsing, etc. The characteristics of the services is part of the modelling such as if data is transmitted intermittently (bursty) or in a continuous stream. Based on these services, the users can be categorized as e.g. a typical office user, a social networking user, or user who streams a large number of videos.
Over the years, in each generation of cellular networks, user service demands are growing exponentially. The existing simulators and traffic dimensioning methods are not flexible in terms of type of traffic. Therefore, multiple simulations for different user density are performed and reasonable results for traffic dimensioning are observed.
We are serving the users by implementing two scheduling algorithms. In general, scheduling means to arrange or plan an event that takes place at a particular time and here it is referred to providing the users with required resources. One of the main difficult tasks is choosing scheduling algorithms out of number of available schemes. As the chosen Round Robin and Maximum throughput algorithms provide a certain result in terms of throughput and latency but the simulator can be expanded with other scheduling algorithms targeting different user characteristics/demands.
When the traffic demands of the users are accurately evaluated, mobile network operators can provide ensured quality of service. In this way, the thesis project work can be used as a useful tool for evaluating the new user traffic demands in the upcoming 5G technology as well. Hence, this will lead to a positive impact on the society as the service demands can be guaranteed to be fulfilled. (Less)
