... (MAC) problem is contention-based protocols in which multiple transmitters simultaneously attempt to access the wireless medium and operate under rules that provide enough opportunities for all nodes to transmit. Examples of such protocols in packet radio networks are ALOHA [3], MACAW [4], and CSMA/ ...

An RTS-id frame is simply a standard RTS frame extended to include a packet ID. With RTS-id, howev ...
