The energy efficient design of wireless sensor networks necessitates optimizations at both the system and individual node level. Node-level energy conservation and power aware decisions can lead to better overall performance and may complement any power saving techniques employed in the network infrastructure. A computationally efficient, polynomial shift algorithm that enables energy aware decisions under dynamic load conditions for wireless sensor nodes is presented. The corresponding energy model accurately approximates the energy decay characteristics for applications exhibiting different energy usage profiles. It adapts to the prevailing load conditions, and can be used by applications supporting self-learnt or over-the-air reconfiguration of nodes within the wireless sensor network. The model's computational complexity is such that it can be computed in runtime configurations on the Mica family of motes.
