- Holistically Application-Aware Multi-dimensional Cognitive Radio (HAMCR)
Principal Investigator: Arslan and Gitlin [and Haas (Cornell)
Granting Agency: NSF
HAMCR is an application-aware cognitive radio with new technology that enables substantial growth in the capacity of wireless networks, with support for diverse applications, without additional spectrum. HAMCR maximizes spectrum utilization by trading off the spectral resource allocations of connections for the application-level QoS, while still maintaining acceptable levels of QoS for the users of the underlying applications, thus satisfying an increased number of users in times of shortage of spectral resources. This work led to several papers and conference presentations and was the subject of Chao He’s PhD dissertation.
