Abstract

This paper presents a power-aware on-demandrouting protocol called PAOD, which aims to maximizethe system lifetime of MANET. In PAOD, the source isable to anticipate the traffic of the request, and eachnode on the route makes energy reservation according tothe anticipated traffic. Since a node knows not only itsphysical residual energy, but also the expected energypossibly to be consumed in the future, it will report itsenergy status more accurately. A new cost function isused in route selection, which takes both shortest-hopand maximum-lifetime into consideration. Some filtermechanisms are proposed based on an energy thresholdfunction, which can remarkably reduce the overheadcosts, and improve the performance of PAOD. A novelmetric & the standard deviation of node energy is usedin the simulation experiments to evaluate the balance ofenergy consumption in the candidate protocols.Simulation results show that, the energy consumption inPAOD is more balanced than in the common on-demandprotocols, and PAOD is with much longer system lifetime,along with higher delivery rate than the common ones.
