VISION With the emergence of new micro-scale sensor technology, deployment of large number of inexpensive, small-scale,    self-organizing, fault tolerant, multi-modal network of sensors scattered over a large terrain is achievable.  Such sensor networks can significantly improve military battlefield command, control, communications, computing, intelligence, surveillance, reconnaissance, and targeting systems.  In the rapidly changing battlefields, interoperatability of distributed sensory system is not only vital to allow reliable assessment of the correct terrain situation critical for strategic decision-making, but also when counteraction is warranted by the actions of the adversary.  Our Center's vision is to exploit potentials of data fusion techniques for advancement of fundamental understanding of sensor networks scalability, distributed sensing behaviors, fault tolerance schemes, hierarchical communication protocols, sensor network informatics, and power efficient fusion techniques in highly uncertain environment.  In particular, our research is focused on  severely constrained sensor with limited functionality in energy, sensing, computation power, and communication capabilities.
