Ad Hoc Network Communication Protocol with Power Control

In the described scenario, we assume mobile nodes in the ad hoc network maintain constant transmission power PTx. For data transmission, nodes first perform channel sensing by measuring received signal power X, where X = I + N (I represents interference and N denotes noise). Transmission is authorized only when X < INThre, with INThre being the background noise threshold. The simulation configuration sets fixed parameters: PTx = 1W per node, receiver sensitivity Smin = -80 dBm, minimum signal quality requirement γ_min = 2 dB, and system noise threshold INThre = 1.2e-10. From an implementation perspective, this logic can be coded using a conditional statement that checks the channel state before initiating transmission. The carrier sensing mechanism typically involves continuous RSSI (Received Signal Strength Indication) monitoring, where the transmission function only executes when the measured power falls below the predefined threshold. These established parameters enable further analysis and research on network performance metrics like packet delivery ratio and collision probability.
