Extreme Densification of Wireless Networks

Investigators: Gustavo de Veciana (ECE, UT Austin), Ramesh Johari (MSE, Stanford), Sanjay Shakkottai (ECE, UT Austin), and Lili Qiu (CS, UT Austin)
Students and Participants : Wei Dong (UT Austin CS), Subhashini Krisnasamy (UT Austin ECE), Rajat Sen (UT Austin ECE), Zheng Lu (UT Austin ECE), Yicong Wang (UT Austin ECE), Pranav Mahdadi (UT Austin ECE), Swati Rallapalli (UT Austin CS), Sangki Yun (UT Austin CS),
Support: This project is supported by the National Science Foundation Award CNS-1343383.

Goal: This project supports research in 5G wireless networks. Network densification - where a multitude of base-stations and access points with overlapping wireless footprints and disparate capabilities pervade the physical domain - is the way forward towards meeting the tremendous demand for mobile data. The main objective of the proposed research is to reevaluate the manner in which wireless networks are engineered and spectrum usage is managed so as to exploit dense access infrastructure. With this resarch effort we expect to make contributions in three areas:
