- Dynamically Adaptive Multi-Modal Sensor Fusion in Urban Environments
A sensor network operates on an infrastructure of sensing, computation, and communication, through which it perceives the evolution of physical dynamic processes in its environment. It is data centric  because data from sensor nodes are the most important to this application. A common characteristic of information fusion in sensor networks is that data streamed from di¡erent sources are brought together through a communication network. Ÿe following factors need to be taken into account:
• Typically, there are thousands of sensor nodes in a wireless sensor network. It is almost impossible to have a global centralized fusion center. In other words, the data fusion scheme has to be designed and implemented in a distributed fashion for wireless sensor networks.
