Description: Unlike infrastructure based wireless networks, nodes
in mobile ad hoc networks (MANETs) will also have to act as
intermediate nodes for data routing. These additional
transmissions will further drain the power resources of mobile
nodes which are anyway likely to be running on limited battery
power. This paper proposes a Power-Aware Ad hoc On-demand
Distance Vector routing protocol (PAW-AODV) for such power
limited applications. This uses the overall power resources of the
system more efficiently than the standard AODV protocol by
choosing routes based on a power-based cost function. We
implement our proposed PAW-AODV protocol by suitably
modifying AODV and study it through simulations using
QUALNET.
