Detailed Description

Test case for the V2V Highway channel condition models using a fully probabilistic model to determine LOS, NLOS and NLOSv states.

The test determines the channel condition multiple times, estimates the LOS and NLOS probabilities and compares them with the values given by M. Boban, X.Gong, and W. Xu, “Modeling the evolution of line-of-sight blockage for V2V channels,” in IEEE 84th Vehicular Technology Conference (VTC-Fall), 2016. Methodology from channel-condition-model- test-suite.cc is used, extended to a system with three states.

◆ EvaluateChannelCondition()

void V2vHighwayProbChCondModelTestCase::EvaluateChannelCondition ( Ptr< MobilityModel a,
Ptr< MobilityModel b 
)
private

Evaluates the channel condition between two nodes by calling the method GetChannelCondition on m_condModel.

If the channel condition is LOS it increments m_numLos, if NLOS it increments m_numNlos

Parameters
athe mobility model of the first node
bthe mobility model of the second node
