- GEOX:Mobile phones are carried out by significant number of population and provide new dimensions of interconnectedness between people, places, and the environment. In this work, we will investigate an analytical methodology to study complex spatial and temporal dynamic of a population by using coarse location information from their mobile phones. By aggregating the geo-traces of individuals, we build a network of interconnected regions. We will study properties of the regional interconnection network and its temporal characteristics. While our study will be a significant contribution in and of itself, we believe that it has broader impact on other science domains such as epidemiology, transportation network planning and urban planning which are interested in large scale mobility of the population and their interaction with the environment.(Additional Information)
- CYCLOPS: Wireless image networks have been attracting increasing research interest due to improvements in imaging microelectronics, processing computation, and wireless networking. In recognition of the importance and richness of the imaging modality, our recent work at Center for Embedded Networked Sensing has studied large-scale distributed image sensing. Our research has not only led to perhaps the most widely used first generation wireless sensor platform capable of image sensing, Cyclops, but through pilot applications and system studies has provided us with a wealth of data and insight into image network challenges and opportunities. Cyclops, which we reported previously, has been used extensively by large body of researchers at CENS and the broader sensor network community to investigate application of computer vision techniques to generate high-quality information from time-series of relatively low-resolution images, study low power computation paradigm, explore vision architectures and system issues, and analyze communication vs. computation constraints. Additionally, Cyclops has also brought together an elite group of interdisciplinary researchers to investigate the application of image network technology in a wide range of environmental biology and ecology application. As reported earlier in this manuscript, there are currently multiple system development and deployment activities underway at CENS that consist of a heterogeneous network of Cyclops and environmental sensors in the context of biology and ecology applications.(Additional Information)

Networked Info-mechanical Systems (NIMS) project explores the interaction of mobile and static wireless sensor networks, in the context of environmental science monitoring problems. NIMS uses infrastructure-assistedmobility to enable controlled movement with reduced uncertainty, facilitate energy transport, and provide easy access in the outdoor environmental science experiments. NIMS project is funded by National Science Foundation (NFS) and has received widespread attention in environmental science community for real world experimentation. (Additional Information)
Robomote project investigates proper platforms for large scale mobile sensor network experiments. In this project, we designed low-power wireless robots and a table-top tesbed that incorporates a colony of such robots. A top viewing camera used as a ground-truth system, localizes and tracks color -marked robots. We investigated distributed mobile systems on our experimental testbed, including analysis of maximization of the coverage in mobile sensor networks and energy harvesting issues.
