Abstract: The transmission range that achieves the most economical
use of energy in wireless ad hoc networks is studied for
uniformly distributed network nodes. By assuming the existence
of forwarding neighbors and the knowledge of their locations, the
average per-hop packet progress for a transmission range that
is universal for all nodes is derived. This progress is then used
to identify the optimal per-hop transmission range that gives the
maximal energy efficiency. Equipped with this analytical result,
the relation between the most energy-economical transmission
range and the node density, as well as the path loss exponent,
is numerically investigated. It is observed that when the path
loss exponent is high (such as four), the optimal transmission
ranges are almost identical over the range of node densities that
we studied. However, when the path loss exponent is only two,
the optimal transmission range decreases noticeably as the node
density increases. Simulation results also confirm the optimality
of the per-hop transmission range that we found analytically.
