Predictable, Real-Time Communication for Wireless Networked Sensing and Control Hongwei Zhang  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 p/DSRC, WAVE  Smart grid IEEE g, 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 computing
