MAC Design in MIMO Ad Hoc Networks Based on Three Types of CTS Packets

Parallel RTS Processing MAC Protocol (PRP-MAC) can improve network throughput, but data packets are not always sent in a synchronized way. So PRP-MAC still produces the packet collisions in the network, which impact the performance of the network. In this paper, we proposed an improved PRP-MAC called IPRP-MAC protocol. This protocol can avoid collisions by using 3 types of CTS packets which are used to make sure the transmitters sent the data packets synchronously. Finally, the simulation results show that IPRP-MAC can enhance the network throughput compared to PRP-MAC.
