We define techniques to compute energy-efficient reliable
paths within the framework of on-demand routing protocols.
The choice of energy-efficient reliable paths depend on link error
rates on different wireless links, which in turn depend on channel
noise. We show how our scheme accounts for such channel
characteristics in computing such paths. Additionally, we perform
a detailed study of the AODV protocol and our energy-efficient
variants, under various noise and node mobility conditions. Our
results show that even in low noise environments there are
specific scenarios where an unmodified on-demand protocol will
achieve significantly lower throughput in comparison to our
modified variants. Our results show that our proposed variants of
on-demand routing protocols can achieve orders of magnitude
improvement in energy-efficiency of reliable data paths.
