Hongwei Zhang, Wayne State University, Feb. 26, 2013
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
network GENI Racks for cloud
