Abstract

This paper proposes a new multi-channel MAC protocol with power control for ad hoc networks. First, the code channel is divided into common channel, broadcast channel and data channel while code synchronization is dynamically implemented through RTS/CTS handshake. In order to decrease handshake cost and avoid code channel switching frequently, Dual Reservation scheme is proposed through ACK Piggybacking. And furthermore, dynamic power control mechanism is implemented to reduce near-far interference. Besides, broadcast is well supported by an out-of-band busy tone. Compared with IEEE 802.11 DCF protocol, the simulation results show that the proposed mechanism can achieve better performance of network throughput
