Energy Characterization of the Stargate Sensor Network Gateway
Source: University of California
This paper presents a new energy estimation model for sensor network intermediate nodes (i.e. the Crossbow XScale Stargate). Such devices are battery powered and resource constrained and commonly employed as communication, processing, and gateway elements within sensor networks. Understanding and accurately characterizing the energy behavior of such devices is the key to conserving the battery life of sensor systems. This paper presents a macro-model for estimating the energy consumption of the device as a whole that couples estimation techniques for computation and communication.
