| Popis: | IEEE 802.11 prohibits an exposed node from transmitting any packet until the end of its NAV (Network Allocation Vector). Some trials have been proposed to enable an exposed node, called secondary sender, to transmit its packets in parallel with a primary sender which reserved a wireless channel in advance through RTS/CTS exchange. However, they did not cope with the existence of interference ranges, while they considered only that of transmission ranges. We therefore propose our P-MAC (Parallel MAC) protocol to enable an exposed node to determine whether or not it can succeed in transmitting its data without any collision. Simulation study proves that P-MAC is superior to other schemes in terms of performance metrics. |
