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.
