1. Presented by: Mahmoud Khairy “Designing Wireless Sensor Networks as a Shared Resourcefor Sustainable Development”e.g. Water Quality Monitoring Application

2. The Main Idea • WSNs are becoming cheaper, but the sensors themselves remain the most expensive component. • WSNs have great potential to be utilized as a shared resource • on-board processing • ad-hoc networking capabilities.

3. The Main Idea • Sensor sharing will allow many people to benefit from sensor network data collection, even with minimal sensor resources. How? • Emulating Density. • Dense to Sparse Deployments. • Short Deployment Cycles.

4. The Main Achievements • In Bangladesh, groundwater is dangerously contaminated with arsenic. • Hypothesis: The influx of dissolved arsenic to ground water is greatly enhanced where irrigation for rice cultivation provides the primary source of aquifer recharge. • We want to aid in validating this hypothesis.

5. The Main Achievements • In Palmdale, California • Water scarcity in arid and semi-arid regions. • Reuse of treated wastewater! • Use WSN at the water reuse site. • Ensuring that environmental regulations are being met. • Providing feedback to a water control system. • Optimize water flow • Minimize chemical penetration into the subsurface.

6. The Challenges • Algorithm Issues • Robust and Interactive Deployment Algorithms • Detecting Data Disruption and Faults • Monitoring Network Health • Rapidly Deployable Systems
