Abstract

Multi-channel research in wireless ad hoc networks has drawn more attention in recent years. Several MAC protocols have been proposed for multi-channel access. However, they either suffer from additional hardware and algorithm cost or weak broadcast support. In this paper, a dual reservation MAC protocol based on CDMA (DRMC) is proposed to solve those problems. Code synchronization is dynamically implemented through RTS/CTS handshake. Once communication is set up, both sides can reserve resource through piggyback. And furthermore, broadcast messages are well supported by an out-of-band busy tone. According to simulation results, we have validated that DRMC performs significantly better than IEEE 802.11 standard which provides multiple channels while its MAC is still designed for a single channel
