The Unit Disk Graph radio signal propagation model uses circle centered at the transmitting mode to simulate radio coverage.

The reception success probability normally depends on the distance d between the transmitting and the receiving node, and is calculated using the formula: P(success) = 1.0 - d^2 * (1.0 - UDGM_RX_SUCCESS), where UDGM_RX_SUCCESS is a configuration value.

If UDGM_CONSTANT_LOSS is enabled, the reception success probability is constant everywhere in the unit disk.

Configuration parameters

  • UDGM_TRANSMIT_RANGE_M - The maximum transmission range, in meters. Positive number, default: 50.0.
  • UDGM_RX_SUCCESS - The reception success probability at the edge of the unit disk. Number from 0.0 to 1.0, default: 1.0.
  • UDGM_CONSTANT_LOSS - Is the reception success probability independent from the distance? Boolean, default: false.
  • TX_POWER_DBM - Transmission power in dBm. A number, default: 0.
