Figure 12. Throughput comparison in 500×500 scenario with 6 channels

To demonstrate the performance benefit of
using multiple channels in wireless networks, we
plotted the average throughput of H-MAC and
LCM-MAC, with varying number of channels ( m )
and compared them against single channel 802.11.
Single channel 802.11 is only used for baseline

comparison. The earlier mentioned scenario with
100 nodes in 500 × 500 m area is used for this plot.
In Figure 14 note that H-MAC's performance
increases almost linearly with increase in number
of channels. This demonstrates the efficiency
of the H-MAC scheme. It does not face control
channel bottleneck, nor does it face any control
