A hybrid wireless networking testbed leveraging Software Defined Networking on Software Defined Radio
Abstract
Recent advances such as wireless SDN, mobile edge computing, and novel suites of SDR nodes and sensors, create an unprecedented opportunity for fully softwarized wireless networks. Motivated by these developments, our goal in this proposal is to build a wireless testbed for experimenting with Software-defined Tactical edge-Networks (STeNs). The latter can emerge through the smart orchestration of these cutting-edge technologies and have the potential to support a rich set of military communication scenarios. The testbed will comprise SDN switches, SDR wireless infrastructure nodes, SDN/SDR-enhanced user terminals, SDN-compatible sensors, cloud computing infrastructure and a lightweight portable LTE core. This equipment will be interconnected and will operate in full sync, creating this way an end-to-end softwarized hybrid communication system.We will use this state-of-the-art testbed to evaluate novel architectures for the operation of STeNs. Namely, a set of important problems will be investigated, such as the placement of SDN controllers, the design of dynamic resource allocation mechanisms, and the development of information-centric network management policies. Various realistic and complex military scenarios will be considered, where these wireless networks operate in independent mode or are part of larger coalition networks, and their information-centric mission is (partially) supported by cloud computing facilities or relies in fully-distributed mechanisms. In every case, the testbed will enable the measurement of overheads and the characterization of performance limits, and eventually it will allow the analysis of the design space of this next-generation of tactical networks.The testbed will have invaluable educational benefits as it will train undergraduate/graduate students and youngresearchers in SDN and SDR cutting-edgetechnologies, and it will introduce them to the most challenging research questions that are pertinent to tactical wireless networks. Equally important, the students will be trained in testbed-based hands-on experimentation, a prerequisite for conducting high quality research in wireless networks.The testbed will have invaluable educational benefits as it will train undergraduate/graduate students and youngresearchers in SDN and SDR cutting-edgetechnologies, and it will introduce them to the most challenging research questions that are pertinent to tactical wireless networks.
