This paper proposes a novel multichannel medium access control (MAC) protocol based on CDMA that improves network performance and reduces collision probability in wireless ad hoc networks. In the scheme, the code channel is divided into common channel, broadcast channel and several data channels. Simulation results show that the proposed protocol can achieve significantly better performance than the...
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...
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...
