KanseiGENI Team: Virtualizing and Federating Next-Generation Wireless Sensor Network Infrastructures
The KanseiGENI team, led by Anish Arora and Rajiv Ramnath from Ohio State University and Hongwei Zhang from Wayne State University, is working to provide GENI researchers with programmability, virtualization, and slice-based experimentation across a nation-wide federation of autonomous wireless sensor network (WSN) infrastructures within the ORCA control framework.
The GENI-enabled Kansei WSN infrastructure has been operational and in active use by the community since June 2009. As a next step, the KanseiGENI software package has been used to GENI-enable the NetEye WSN infrastructure at Wayne State and the PeopleNet mobile WSN infrastructure at Ohio State. Soon, the KanseiGENI package will also be used by another GENI project, led by Andy Li from Oklahoma State University, to establish an outdoor experimentation infrastructure of both sensor nodes and robotic platforms on that campus.
These KanseiGENI experimentation infrastructures provide a rich set of features for researchers, including:
- An integrated researcher portal that allows authenticated users to interact with a wide range of WSN fabrics such as XSM, TelosB, Stargate, and laptop arrays,
- Support for both web-based and programmatic interactions, such as experiment scheduling and results retrieval,
- A scripting environment for composing long-running, complex, and/or phased experiments,
- And, the Kansei Doctor, which periodically measures the number of available nodes, their health, radio link quality, and other relevant networking metrics.
Each of the KanseiGENI infrastructures has been fully integrated with the GENI ORCA control framework allowing interoperability between the KanseiGENI researcher portal (running an ORCA service manager), the site manager for each infrastructure, and a clearinghouse hosted by the ORCA group at RENCI (led by Ilia Baldine). This allows access by remote GENI researchers to each infrastructure. Currently, work is underway to extend the researcher portal to enable federated experiments involving both the Kansei infrastructure at Ohio State and the NetEye infrastructure at Wayne State.
