3 Motivation and Goals Motivation and Goals Motivation: Provide an OMNeT++ interference model based on real measurements. Goal: A method to include interference scenarios into OMNeT++ simulations in a non-intrusive way.
4 Motivation and Goals Motivation and Goals Motivation: Provide an OMNeT++ interference model based on real measurements. Goal: A method to include interference scenarios into OMNeT++ simulations in a non-intrusive way.
5 Method Description Sampling Sampling Figure: The Probe Based on a set of Probes to capture traffic. Captured traffic trace content: Source Address (MAC) Reception Timestamp Received Signal Power Transmission Datarate Packet Size
6 Method Description Distance Estimation Distance Estimation Source Probe - Source distance estimation based on Reception Signal Power sampling and calculation by using Free-Space Pathloss Propagation Model. Probe
7 Method Description Localization of the Sources Localization of the Sources Based on: Triangulation by using Probes positions and the Distance between the Detected Sources from each Probe. Sparse-Matrix Clusterization Analysis.
8 Method Description Virtual Position Virtual Position Position required to measure the same signal strength without obstacles in the line-of-sight.
9 Method Description Virtual Position Sparse-Matrix Cluster Analysis The estimations of the Detected Sources Position s are clusterized according how close they are (euclidean distance).
10 Integration into the Simulation Integration into the Simulation Traffic Generation: From recorded traces. Injected from the estimated source s positions. INET Framework: Traffic Generation. Shadow Sources (light or complete) Channel Controller Module. Wifi World Compound Module.
11 Method Validation Method Validation Figure: Experimental Scenario
12 Method Validation Method Validation Number of Samples Reception Power (dbm) Figure: Multiple Range Test for Reception Power Estimation
13 Method Validation Method Validation Difference (%) Source 1 Source 2 Source 3 Source 4 Source 5 Source 6 Source 7 Source 8 Source 9 Source 10 Detected Sources P1 P2 P3 P4 Figure: Differences Between Measured and Simulated Values 62.5% under 10% error. 13.5% between 10% and 20% error. 5% was 100% wrong.

18 Conclusions Summary We presented a method to introduce interference scenarios in studied systems based on observations. Interfering traffic characterizations come from a real scenario (recorded scene). The method is easily repeatable with commodity hardware. Permits to evaluate two types of interaction between the Studied System and the interfering background traffic How the system reacts in front of the interferiring traffic. (one way interaction). How the interferiring traffic and the system affect each other. (two way interaction) Further Work Improve precision of the location estimation. Validate with more scenes and measure differences.
