The use of multiple channels for transmissions has raised several challenges, for example, multi-channel hidden terminal problem, channel switching delay and control channel saturation problem. Dedicated control channel techniques simplify channel coordination by eliminating the need for synchronization; however the control channel may become the bottleneck for the performance of the network. A better trade off which can solve the coordination problem, and can mitigate the control channel bottleneck is desirable. Least Channel Variant Multi-channel MAC (LCV-MMAC) is a multi-channel MAC based on IEEE 802.11 MAC. The novel part of this protocol is the channel assignment technique, where a mechanism to avoid unnecessary channel assignment and thus channel switching is used.
