A Value-Based Energy Manager for Wireless Sensor Networks

Recent research in Wireless Sensor Networks (WSNs) focuses on the definition of a re-useable software module to encapsulate energy management concerns. One such paper defines an Energy Management Architecture (EMA), which schedules application tasks in terms of static priorities and a simple request/grant API. Under EMA, application goals are expressed in terms of a constant priority structure. The priority structure codifies the application programmer's decision about the relative value of task activations. EMA simplifies the process of designing a WSN application with predictably deteriorating performance under various energy conditions.
