***SMARTGEO***
SmartGeo (an NSF IGERT project) is an interdisciplinary program in the development of intelligent geosystems – enabling engineered and natural earth structures and environments that sense their environment and adapt to improve performance. Research efforts focus on using wireless sensor networks to advance intelligent geoconstruction, intelligent earth dams & levees, and remediation of contaminated soil and water. In one project, we research sensing and monitoring techniques to assess early onset of internal erosion of an earth dam by fusing geophysical, geotechnical and remote sensing data. In other project, we are developing a system that integrates multiple forms of sensed data, models, and techniques to develop a closed-loop uranium bioremediation system. A CI Fellow interested in wireless sensor networks, data mining, graphics/visualization, or machine learning would be a welcome addition to this project.
***NETWORK SIMULATION CREDIBILITY***
Simulation is the research tool of choice for a majority of the mobile ad hoc network (MANET) community. However, while the use of simulation has increased, the credibility of the simulation results has decreased. This work focuses on the development of tools that researchers can use to improve the credibility of their simulation work. For example, one focus of our work is to provide researchers with models that allow them to easily construct rigorous MANET simulation scenarios. The input to our models is the desired values for three metrics (e.g., average shortest path hop count); our models then output parameters for a simulation scenario that approximately meet the researchers target values for the metrics. Examples of other tools developed include visualization and realistic mobility models based on GPS trace data. A CI Fellow interested in impacting the way that researchers do network simulation would be welcome.
***COOPERATIVE BEAMFORMING***
Cooperative beamforming (CB) is a novel technique that enables high throughput and power efficient communications in a secure manner. CB consists of two stages. In the first stage, the sources share their data with neighboring nodes via low-power communications. Various approaches for such information sharing are considered, with a goal to minimize queuing delays, conserve energy, and achieve high throughput. In the second stage, the cooperative nodes apply a weight to the signal received during first stage, and transmit. The weights are such that a specific objective criterion (e.g., signal to interference at the destination) is maximized. In CB, although each node uses low power, all nodes together can deliver high power to a faraway destination. This research project is interdisciplinary and combines concepts in signal processing, economics, decision theory, optimization, information theory, communications, and networking. Our efforts at the Colorado School of Mines is focused on synchronization of the wireless communications and other research issues associated with the MAC layer. A CI Fellow interested in signal processing, wireless security, or communications would be a welcome addition to this project.
