In this paper, we present a novel location-aware multi-channel Medium Access Control (MAC) protocol for large-scale dense Mobile Ad Hoc Networks (MANETs) based on a scalable two-phase coding scheme, where the first-phase code is used for differentiating adjacent cells and the second-phase code is employed for distinguishing nodes in one specific cell. It eliminates the hidden terminal problem (HTP) during data transmission without requiring periodical exchange of neighborhood information. Furthermore, we introduce the mechanism of collision resolution in the control channel. We analyze the performance of the proposed protocol in terms of control overhead. Its theoretical results are confirmed by simulations and it is demonstrated that the new protocol significantly outperforms the classical Code Division Multiple Access (CDMA) based multi-channel MAC protocols.
