A note on local receive channel scheduling versus transmit channel scheduling in wireless multi-channel ad hoc networks

Two strategies for FDMA channel assignment in multi-channel ad hoc networks, where transmissions occur over a maximum distance r
_max
, are compared: local transmit channel and local receive channel FDMA orthogonalization. While transmit scheduling yields higher gains, it also requires a contention resolution mechanism on the MAC layer. Receive scheduling does not necessarily require contention resolution, but performs worse in the relevant low outage regime.
