Distributed sensing systems, which are networks of tiny sensing devices, hold the promise of providing an inexpensive, non-intrusive means to understand phenomena that exhibit spatial and temporal variations at multiple scales. Such systems are envisioned under two general architectures: Distributed systems that perform distributed sensing and in-network data processing to complete some desired tasks such as hypothesis testing or target tracking, and decentralized systems that perform

In this work we also focus on the architecture that performs in-network data processing. While significant effort over the last decade has produced the necessary infrastructure for deployment, efficient monitoring requires development of new distributed signal processing and decision making approaches in wirelessly networked, power limited regimes. We consider the example of a sensor network for
