In this paper, the authors present a Power-Aware Ad-hoc On-demand Multipath Distance Vector routing protocol called PA-AOMDV, which aims to maximize the system lifetime of sensor networks. AOMDV has the ability to discover multiple routes to a host and switch between them, if an active route is becoming weak and there is a risk that it will disappear. In PA-AOMDV, the source is able to anticipate the traffic of the request, and each node on the route makes energy reservation according to the anticipated traffic. Since a node knows not only its physical residual energy, but also the expected energy possibly to be consumed in the future, it will report its energy status more accurately.
