Event-Driven Wakeup Receivers: Applications and Design Challenges

This paper presents an overview of the design considerations and challenges of event-driven wakeup receivers as well as an analysis of state-of-the-art (SOA) research. We consider advantages and disadvantages of the commonly utilized architectures in these systems as well as presenting big picture perspectives from an application standpoint. This paper focuses on event-driven scenarios where the activity factor of a node is so low that its standby power consumption, which sets the power floor in its sleep mode, becomes a dominant factor in determining the node lifetime.
