Power-Aware Architecture for Wireless Sensor Networks
Recent years have seen a burgeoning interest in embedded wireless sensor networks with applications ranging from habitat monitoring to medical applications. Wireless sensor networks have several important attributes that require special attention to device design. These include the need for inexpensive, long-lasting, highly reliable devices coupled with very low performance requirements. Ultimately, the “holy grail” of this design space is a truly untethered device that operates off of energy scavenged from the ambient environment. We taken an application-driven approach to the architectural design and implementation of a wireless sensor device that recognizes the event-driven nature of many sensor-network workloads. The chip has been taped out with measurement results currently under submission.Publications: [ISCA’05], [CASES’09],[JETCAS ’11]
