Wireless Networking research objectives: Developing novel algorithms and techniques for efficient communication over multi-hop wireless networks. We are specifically interested in energy-efficient communication and networking.

General research perspective : Classical communication theory does not address random arrivals of finite-length data. Moreover, when multiple independent data streams (belonging to multiple uses, for example) need to be served on a shared medium, such as the multiple-antenna downlink, one obtains a multiprocessor queueing system of a new kind. We try to combine tools from communication, networking, and information theories toward novel problem formulations and theoretical advances to optimize multiuser communication with random data arrival processes.            


Current project :

E-CROPS--- Energy Harvesting Communication Networks: Optimization and Demonstration, ERA-NET 2012-2015

 

Completed projects :

1.      Principles and  Experimental Implementation toward Energy-Efficient Design of Wireless Networks, TUBITAK grant, 2011-2014.

2.      Novel Transmission Techniques for Energy Harvesting Communication Systems, Funded by Turk Telekom, 2012-2013

3.      MIMO Networking: From Principles to Protocols. (Funded by NSF, under the Computing and Communications Foundations Program, 2006-2010.) A motivating outcome was getting low-complexity scheduling algorithms as the number of users of the MIMO link grows large. This technique relies on the existence of near-multually orthogonal sets, or “NEMO”, described in this paper.

4.        Minimum Energy High Performance Wireless Communication Network Design: Inter-layer Optimization and Algorithms. (Funded by a TUBITAK "Kariyer" Award, 2007-2010.)

One of the outcomes was a wireless sensor network testbed (here are some pictures) with MICAz motes equipped with magnetic sensors.

5.      5. Narrowband Wireless Ad-hoc Network Design. (Funded by ASELSAN 2009-2010)

6.      Design of a novel highly reliable and scalable wireless ad-hoc network protocol suite.

7.       Energy Efficient Wireless Mobile Networking Technologies to Enable Smart Infrastructures, IBM Faculty Award, 2010.
