Ad Hoc Network Communication Protocol with Power Control

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.

Constant Transmission Power for Mobile Nodes

In our simulation setup, each mobile node is configured with a constant transmission power of PTx = 1W. The receiver sensitivity at the receiving node is set to Smin = -80 dBm, with a minimum signal quality requirement of γ_min = 2 dB, and a system background noise threshold of INThre = 1.2e-10. These parameters are typically implemented as global constants in the simulation code to ensure consistent physical layer behavior across all nodes.
