Title Simulation of Latency in Backhaul Networks for 5G
Abstract The continuous development of wireless communication technologies leads to a growing number of connected devices and increasing real-time requirements. These rising demands on communication networks require heavy network densification, which in turn leads to increased costs. The use of wireless backhaul technologies, in comparison to wired ones, offers a promising alternative to meet the requirements of state of the art networks while reducing costs. The design of backhaul networks is therefore becoming increasingly important. Accordingly a simulation environment for comparing three different backhaul concepts, for the 5G technologie, is  implemented. The three different concepts are namely fiber and two wireless concepts: Sub-6GHz and mmWave. The main objective of this work is the simulation of a 5G network on a selected example in a limited region. As area of study the university square of the city of Magdeburg was chosen. The work builds upon research on backhaul networks and the technologies employed. Furthermore, suitable simulation tools were identified and a simulation environment was selected, employing SUMO for the traffic simulation and OMNeT++ with Veins as interface for the network simulation. The models for all three backhaul concepts (fiber, sub-6GHz and mmWave) were implemented for Magdeburg University Square. OpenStreetMap data was imported for the traffic simulation and a traffic volume according to the statistical reports of the city of Magdeburg, random movements of pedestrians and tram and bus traffic according to the timetables of local public transport were taken into account. The evaluation was carried out for the performance parameters latency, jitter and frameloss to assess reliability.
