Abstract
We discuss a new multichannel coordination and scheduling challenge called the Multichannel Scheduling
Cost (MSC). It is caused by the inability of the control channel to schedule simultaneous transmissions
resulting in data channels lying idle and their bandwidth underutilized. As a result, wasted bandwidth
increases as the number of data channels increases. To address this challenge, a cyclic scheduling
Algorithm (CSA) is proposed. It employs one dedicated signaling channel and 4 data channels. It is
premised on a proactive channel reservation scheme which reduces the idleness of channels. The scheme
ensures that data channels are reserved while they are still busy. The data channels are reserved while
their remaining transmission duration is equal to the virtual carrier sensing duration. This gives the next
pair sufficient time to reserve the current data channel before it becomes available, limiting the MSC to the
first cycle. The simulation results show a performance benefit of the CSA scheme in addressing the effects
of the MSC.
