A channel access protocol for multihop wireless networks with multiple channels

The Group Allocation Multihop Multiple Access (GAMMA) protocol is presented; this protocol schedules data traffic over a multihop, multi-channel, wireless network. GAMMA provides excellent performance and remains stable under all network load levels by dividing the channel into cycles; each cycle is composed of a combination of contention and data slots. Every station in the network has a unique channel for receiving data. Each station maintains a set of stations called the "transmission group", only members of this group are allowed to transmit data collision-free to the station maintaining the group.
