We define a Quality-of-Power-Service (QoPS) metric to evaluate the efficiency of power-aware Unicast routing pro tocols increase the longevity of ad hoc networks. QoPS metric is applied to different position-based power-aware Unicast routing protocols. Our simulation results con rm that power-relative distribution of data streams in multi path Unicast routing protocols consume substantially less energy from individual nodes than from other distribution methods and thus increase the network's lifetime. More over, the experiments show that multi-path protocols pro vide excellent scalability.
