Abstract

Energy drainage from a node is mainly caused by the power consumption of the nodes communication device. A MAC protocol is the main mechanism to provide efficient access to the shared wireless channel. Directional antennas provide several benefits over several omnidirectional ones including the reduced energy consumption in frame transmissions. In this paper, we study and compare different generic directional virtual carrier sensing schemes (i.e., directional-RTS/CTS) in terms of their energy efficiency and performance. Both analytical and simulation results show that the schemes using directional-RTS and/or directional-CTS are more energy efficient than other schemes.
