Towards Next Generation of Wireless Networking Testbeds
Abstract: Wireless network testbeds are important for realistic, at-scale experimental evaluation of new radio technologies, protocols and network architectures. A number of existing wireless testbeds are being used for experimental research on a wide variety of research topics including dynamic spectrum access, full duplex, massive and distributed MIMO, cmWave and mmWave, cognitive radio networks, DTN, vehicular networks and so on. Increasingly, these testbeds are also being federated to cater to experimenter needs which cannot be fulfilled by a single testbed, and to provide a wider variety of environmental settings at different scales. With a somewhat belated reality check on 5G, larger tests and demonstration sites have become essential in the validation of next generation wireless platforms. We will start this talk with a brief overview of existing and planned large-scale public domain testbed initiatives. This will be followed by a discussion of the impact of increasing complexity of wireless devices and the scale and heterogeneity of the testbeds. We will also present some of the challenges for harmonization and standardization of testbed management frameworks. Of particular interest are ideas on extending publicly available testbeds with 5G related technologies as they become available and how they can be used to address common technological and scientific problems that are related to advanced wireless systems. We will conclude the talk by pointing out some of the key remaining challenges for the successful deployment of next generation of wireless network testbeds.

He is currently the PI for the NSF GENI Wireless project which resulted in campus deployments of LTE/WiMAX base stations at several US universities, and for the NSF CloudLab deployment at Rutgers. He has also been the co-PI and project manager for all three phases of the NSF-supported ORBIT mid-scale testbed project at WINLAB, successfully leading technology development and operations since the testbed was released as a community resource in 2005 and for which the team received the 2008 NSF Alexander Schwarzkopf Prize for Technological Innovation.
