The Perturb and Observe (P&O) method is one of the most commonly used Maximum Power Point Tracking (MPPT) techniques. Its core principle involves periodically increasing or decreasing the photovoltaic array's output voltage (a process called "perturbation"), then observing the resulting output power change direction. If ΔP > 0, it indicates the reference voltage adjustment direction is correct and should continue; if ΔP < 0, it means the adjustment direction is incorrect and must be reversed.

This implementation models an ad hoc network where mobile nodes maintain constant transmission power (PTx = 1W). Each node employs carrier sensing by measuring received signal power X = I + N (interference plus noise) before transmission. Transmission is permitted only when X < INThre (background noise threshold = 1.2e-10). Key parameters include receiver sensitivity Smin = -80 dBm and minimum signal-to-noise ratio γ_min = 2 dB. The simulation implements power control logic through conditional transmission authorization.
