Real-Time Wireless Embedded Systems
Welcome to the Networked Real Time and Embedded Systems Laboratory at UIUC.
Detailed information about our research on Real-Time Wireless Embedded Systems can be found here.
embedded systems like collaborative robots, or distributed control
applications where sensors/actuators are connected wirelessly.
- RI-EDF: Wireless Distributed Control Based on RI-EDF (single hop)
In this work an innovative real-time wireless MAC protocol was designed and a testbed for wireless distributed control was developed.
The real-time wireless protocol is Robust Implicit
Earliest Deadline First (RI-EDF), an EDF-based algorithm for ad-hoc real-time wireless communication.
The intended use of this protocol is for
RT-Chain: Real Time Ad-Hoc Wireless Communication Based on RT-Chains (multi hop)
In this work we designed and developed Real-Time Chains, a new prioritized MAC protocol to support soft real-time data flows in
multi-hop wireless ad-hoc networks. RT-Chain avoids all packet collisions and limits the effect of priority inversions. Furthermore,
it enables high spatial reuse and transmission rate using multiple wireless channels. We fully implemented and validated
the protocol on MICAz hardware.
ALEIS: Assisted Living Embedded Infrastructure
ALEIS is an embedded infrastucture
targeted at Assisted Living Environments. ALEIS uses
RT-Chain protocol and was implemented on MICAz motes. It provides
localization, fall detection as well as an emergency audio
link. In this work, ALEIS demonstrates how a sensor network
enhanced with real-time communication can provide
a reliable, affordable, and non-intrusive solution for real-time monitoring of Assisted
