Wireless networked, closed-loop, real-time sensing and control Sensing, networking, and computing

tightly coupled with the physical process

Connected vehicles IEEE 802.11p/DSRC, WAVE

Smart grid IEEE 802.15.4g, NIST

Industrial monitoring and control

WirelessHART, ISA SP100.11a

Wireless networks as carriers of mission-critical sensing and control information

Stringent requirements on predictable QoS such as reliability and

timeliness

Sponsors: NSF (CAREER, CPS, GENI), Ford Research, GM Research

From passive to active safety: lane departure warning, collision avoidance;

From single-vehicle control to platoon control & integrated infrastructure-vehicle control: networked fuel economy and emission control

From wired intra-vehicle networks to wireless intra-vehicle networks Multiple controller-area-networks (CANs) inside vehicles

50+ kg of wires increased, reduced fuel efficiency Lack of scalability: hundreds of sensors, controllers, and actuators Wiring unreliability: warranty cost, reduced safety

Connected vehicles: inter- and Intra-vehicle sensing and control

Systems research

Sensor network testbeds: NetEye,

KanseiGenie

SDR-based connected-vehicle research

platform

GENI WiMAX research
