The authors propose a rendezvous scheme based on multilevel orthogonal hopping for multi-channel medium access control protocols. Its benefits compared to random hopping are higher throughput due to higher rendezvous probability. Furthermore, it offers improved fairness over other orthogonal hopping schemes. Multi-channel MAC protocols organize and distribute data traffic across multiple channels. Compared to single channel MAC protocols they offer increased throughput, especially in networks with a high number of nodes. A class of multichannel protocols are parallel rendezvous protocols such as SSCH or McMAC, that allow simultaneous transmission agreements to improve performance: each node has its own home channel hopping sequence, so that multiple connections can be negotiated at the same time.
