1. A Network Virtual Machine for Real-Time Coordination Services
Network Virtual Machine (hides complexity of
physical environment - battlefield awareness)
New Ideas
Integration of real-time computing theory, multi-mode MDP, and feedback control theory
Composable and scalable micro-protocols that can self-organize distributed devices into collaborative teams to achieve aggregate goals
New wireless communication protocol to support end-to-end delay
Protocols for dynamic environmental data discovery
Resource management, team formation,
real-time, mobility, power
Heterogeneous Sensors/Actuators/CPUs
Impact
Guaranteed aggregate behavior of NEST systems
Control of mobile sensor/actuator/computer networks
Large scale distributed team coordination
Theory and practice for performance control
Survival of essential services
