Research on MAC Communication Mechanism of Air-to-Ground Data Link Based on 3G: The MSDU Frame Subsection and RTS/CTS Handshake Mechanism

In order to settle the conceal terminal, frequency shift, losing package, mistaking code problems of air-to-ground data link, which were arosed by high speed moving of node and more complicated network enviroment, two important MAC communication mechanism-the MSDU frames subsection and RTS/CTS handshake mechanism-were introduced. Then some simulation experiment were made from little operation and much operation aspects, and some simulation analyse was given. Finally, some useful conclusion is got.
