— We present a dynamic optimization approach to save energy in Wireless Sensor Networks (WSN) at the link level. One of the main sources of energy waste in a WSN is idle listenin...
Abstract—This work addresses the problem of energy allocation over source compression and transmission for a single energy-harvesting sensor. An optimal class of policies is iden...
