Associate Partners-Green Communications

“The energy needed to run communication networks is responsible for approximately the same amount of greenhouse gases as the aviation industry. Making communication equipment more energy efficient is a very difficult research problem but by doing so it can have a huge impact. It is one of the most exciting areas of research in communications and computing.”
—Dr. Gee Rittenhouse, Chairman, GreenTouch

ISR Associate Partners may choose to work with our experts in energy-efficient green communications, a major research initiative at ISR. ISR faculty and their students are working to make the University of Maryland a worldwide hub for green information, communication and computing technologies.

An international workshop on green communications was held in Fall 2010 to define a research agenda and target major research funding in this area. You can view the report from this workshop online.

Through ISR, the University of Maryland is a member of GreenTouch, a major industry-university consortium led by Lucent-Alcatel with more than 50 member institutions. Several major proposals have been pursued by ISR faculty.

The Laboratory on Energy-Efficient Wireless Sensors is a new ISR research facility created with NSF funding. The green communications initiative has connections and areas of overlap with ISR’s Maryland Robotics Center and microsystems initiatives.

Areas of expertise

ISR’s green communications faculty represent the critical areas of communication and information theory, networking, wired and wireless technologies, mobile computing, data centers, energy harvesting, energy reduction and heat removal technologies.

In communication—Communication, information theory, networking and signal processing faculty are developing communication schemes and protocols for wireless systems that harvest natural energy and strive to be energy-neutral. The research involves development of practical protocols as well as fundamental limits for performance. There are joint efforts in investigating the trade-off between communication energy and computation energy and the fundamental limits for total energy expenditure.

In computing—Computing faculty provide critical expertise in energy-aware hardware and software technologies, from mobile devices to data centers. Critical areas such as low-power processor design, energy-efficient implementation of communication protocols and algorithms, run-time power and thermal control methods, energy scavenging systems, efficient heat removal technologies such as fluidics and decentralized cooling are being pursued.

Collaboration examples

ISR researchers collaborate with both large and smaller companies. Here are a few examples of what can be accomplished when you team with us.

  • Hughes Network Systems DirecPC and DirecWay fast broadband internet over satellite protocols
  • Resensys Wireless sensors monitor bridge structural integrity.
  • OnmiSpeech Speech extraction technology improves cellular and other communications.
  • Qualcomm/Flarion Signal processing algorithms led to advances in modem technology, wireless networks, mobile devices.
