Simulator for Mobile Networks SiMoNe


SiMoNe is a simulator for realistic mobile radio networks. Beginning in 2014, SiMoNe has been developed from scratch by researchers of the Department of Mobile Radio Systems. It allows for simulations with a bunch of individual mobile subscribers which follow different movement models, e.g. for vehicular or indoor movements. SiMoNe offers the possibility to simulate 3GPP based networks like GSM, LTE, LTE D2D and 5G as well as IEEE 802 connections like WiFi, 802.11p and 802.15.3d. Different technologies can be combined arbitrarily and investigated under the impact of realistic user applications.


Beside simple hexagon scenarios, complex network topologies in combination with functions of Self-Organising Networks (SON) can also be used and simulated (see “Hannover Scenario”). The performance indicators of the developed solutions can be pre-processed and illustrated using visualisation components. Among these are e.g. the illustration of network parts, graphical refurbishment of network metrics as well as an emulation of the experimental performance on real tablets.





The Hannover scenario


The Hannover scenario is a realistic simulation scenario which was developed at the Institute for Communications Technology and has already been applied in several research activities. It has a dimension of 24 x 20 km² and involves the whole downtown area, most of the periphery of the city and rural areas around Hannover. Important traffic hubs like the main station of the airport are located inside the scenario as well. In order to carry out investigations e.g. for the improvement of supply quality and optimization of network performance, positions of GSM 900 and 1800, LTE 800 and 1800 cells as well as WiFi cells are provided.
