An Architecture for the Next Generation of Networked Sensor Systems

Ramesh Govindan

About the talk:
Over the last five years, sensor network research has seen significant advances in the development of hardware devices and platforms, and in the design of services and infrastructural elements such as routing, localization, and time synchronization. Deployed systems, however, have lagged behind. Existing deployments are small- to medium-scale continuous data acquisition systems in which all sensor data is collected at a central location. This is far from the vision enunciated in early sensor networks work, in which sensor networks incorporate significant in-network processing for energy efficiency; yet attempts to move these deployments closer to the vision have foundered.
In this talk, I will relate our experiences in deploying a wireless structural data acquisition system called Wisden on a large office building. I will then extrapolate from these experiences to outline a plausible architecture for the next generation of networked sensor systems.
