  This paper evaluates the energy consumption of well-known routing protocols,
along with other metrics such as throughput, packet delivery ratio (PDR), and
delay in different scenarios. We consider two other metrics in order to capture
the efficiency of the energy consumption: e-throughput which is the ratio
between the consumed energy and the throughput; and the e-PDR which is the
ratio between the consumed energy and the PDR. We compare four routing
protocols: AODV, OLSR, and HWMP in Reactive and Proactive modes. The number of
nodes is varying between 25 and 81 nodes, with different mobility models.
Simulations are conducted using NS3 and the parameters of a real network
interface card. From the results, AODV presents the lowest energy consumption
and a better e-Throughput. OLSR provides a better e-PDR in mobile scenarios.
With a smaller e-PDR and e-Throughput, the proactive mode of HWMP is more
energy efficient than the reactive mode.
