Looking to simulate a 3-tier heterogeneous network. The base stations in each tier operate in a different frequency band, have a different transmit power and path loss exponent. Some have sector antennas while others have omni antennas. I need to change various handover parameters and see the effect. What may be the best tool for this?
One option to consider is NetSim, and you can look through the following links to get an idea of what is possible:
- 5G library: https://www.tetcos.com/5g.html
- 5G user manual: https://www.tetcos.com/downloads/v14/5G-NR.pdf
- Example Hetnet simulation: https://support.tetcos.com/a/solutions/articles/14000136902
A possibly useful discussion https://www.researchgate.net/post/Modeling_and_simulation_of_5G_HetNets_in_a_network_simulator Regarding handovers NetSim models A3 based handovers. You can change parameters such as handover margin (offset), Time-to-trigger, and handover interruption time.
For information on handover modeling in 5G see https://www.researchgate.net/post/How_exactly_is_the_5G_handover_simulated_in_NetSim
You can see https://support.tetcos.com/support/solutions/articles/14000136902. The article describes simulating 5G heterogeneous networks (HetNets) in NetSim. It details setting up a multi-tier structure with different types of Base Stations (BSs), like macro and small BSs, each with unique frequency, power, and bandwidth settings. The simulation involves configuring pathloss, shadowing, fading, BS association rules, and UE mobility, including handover parameters within/across HetNet tiers. An example provided analyzes the impact of handover margin and time-to-trigger on handover count and sum throughput in a 3-tier 5G HetNet scenario, showing how these parameters affect network performance.
When simulating a HetNet with different tiers in NetSim how can I find out the load on each tier? For example: if tiers operate in different frequency bands and bandwidths, how can I obtain the load on each tier?
See https://www.researchgate.net/post/How_can_I_accurately_determine_the_count_of_handovers_taking_place_within_a_5G_network_when_simulating_with_NetSim/1, its been answered there.
