Monte Carlo simulation is a computational method that uses repeated random sampling to model complex systems and estimate outcomes that are analytically intractable, such as pedestrian movement trajectories governed by stochastic force equations or probabilistic occupancy estimates derived from sparse connection data. In WiFi and CSI sensing research, it matters because real-world environments involve substantial randomness in device behavior, human mobility, and signal propagation, making closed-form solutions impractical; Monte Carlo methods allow researchers to validate models, quantify uncertainty, and test estimators like capture-recapture variants under controlled synthetic conditions before deployment. Key variants relevant to this field include standard random sampling for sensitivity analysis of occupancy models and stochastic simulation of agent-based dynamics, as seen in social force model evaluations where Langevin-driven pedestrian trajectories are sampled across many runs to characterize emergent crowd behavior statistically.
