Performance Analysis of MAC in VDL2 Based on OPNET Simulation
Lin Xia Gao, Zhi Jun Wu · Applied Mechanics and Materials · 2013
As one of VHF data links of ATN, VDL2 is publicly recognized as the next generation data-link in the transition period. The paper focused in the performance research of MAC, of which p-CSMA is the core protocol, based on network simulation. As the precondition of simulation, we build VDL2 model in an integral way and realize MAC process modules in both ground station side and aircraft side applying dynamic process and queue management mechanism. In the paper, Performance targets are defined to evaluate the system performance. Through simulation, trends between parameters and targets are reached and the relationships are revealed between packet delay and throughput\ packets strength.
