lower power than the base case. Thus, as the network size increases, the power
savings due to lower hop count can compensate for the overhead of using RF-I.
Figure 6.30 shows the energy delay product improvement of RF-enhanced
mesh over the base mesh for the four sizes. This figure shows that for UR
and LC traffic patterns when
