The document proposes a Power Controlled Dual Channel (PCDC) medium access protocol for wireless ad hoc networks that aims to increase channel utilization and network throughput while decreasing energy consumption. The protocol builds on IEEE 802.11 by allowing simultaneous transmissions in a neighborhood through dynamic power control based on directional and channel gain information from overheard RTS and CTS packets. Simulation results show the proposed protocol achieves significant increases in channel utilization and end-to-end throughput as well as significant decreases in total energy consumption compared to IEEE 802.11.
