In this talk I will use three data gathering applications, namely long-term habitat monitoring, vital sign monitoring of ambulatory patients inside hospitals, and large-scale monitoring of environmental conditions inside data centers, to illustrate some of the challenges that a network architecture for low-power wireless sensing must address. I will then present elements of such an emerging architecture through a low-power, receiver-based MAC protocol, a multi-channel reliable data dissemination protocol, and a token passing algorithm for contention-free data collection. I will present evaluation results from a combination of simulations, testbed experiments, and network deployments. Finally, the talk will outline mechanism for composing these components to a unified architecture and conclude with a list of remaining system challenges.
