Abstract: The Reactive Sensor Networks project was based on a vision of sensor networks as virtual enterprises. A sensor network would be fielded by the military with certain goals in mind. The chaotic nature of the battlespace guarantees that mission parameters will change. The network would have to adapt in response to environmental constraints. RSN developed multiple technologies to enable the network to adapt to changing mission parameters: a) mobile code daemons support remote tasking of nodes and autonomous software reconfiguration. b) a distributed target-tracking algorithm enables the system to accurately track multiple targets with no single points of failure. c) autonomous configuration of target classification software uses the mobile code infrastructure to choose the classification algorithms that best suit the current mix of targets in the field. d) multiple sensing modalities were integrated into a tracking system at the PSU/ARL sensor network testbed. e) a distributed target counting application was derived and fielded. All approaches were implemented, tested and validated. The project also produced a new design approach for networks of embedded systems using cellular automata based tools. From our experience, these tools support an exploratory approach to system design that is very appropriate for use in implementing sensor networks.
