2. Challenges  What/where to sense  How to connect sensors  How to deal with vastness  How to avoid data explosion  How to deal with heterogeneous data  How to secure data  How to make sensor network robust  How to optimally use data for decision- making and control

3. Research Issues  Modeling interdependencies and correlations between sensor data  Modeling system dynamics  Sensing and communication under energy, bandwidth, complexity constraints  Optimizing commmunication topologies  Fusing heterogeneous data  Distributed/decentralized decision-making and control  Designing robustness to failures, modeling uncertainty and callibration errors
