Sponsored by the National Science Foundation 2 Project Summary ViSE---a Virtualized Sensing Environment---focuses on: –Virtualizing access to sensors that produce high-bandwidth sensor data, such as pan-tilt-zoom video cameras and weather radars, –Integrating sensor virtualization technology into GENI, and –Operating a testbed linked to GENI that enables researchers and end-users to control sensors as part of their experiments. ViSE is affiliated with CASA, an NSF Engineering Research Center focused on Collaborative Adaptive Sensing of the Atmosphere, and shares its mission to "revolutionize the way we observe, understand, and predict hazardous weather.”CASA Accomplishments –Deployed outdoor ViSE nodes in Western Massachusetts –Connected VLAN from ViSE gateway to NLR –Integrated ViSE with Orca/RENCI Clearinghouse (GEC 7/8 Demo) Links ViSE VLAN to resources at RENCI via Starlight –Web portal access to standalone ViSE –Integrating with DiCloud August 6 th, 2010

Sponsored by the National Science Foundation 6 Accomplishments 1: Advancing GENI Spiral 2 Goals Integration – ViSE is using the common RENCI/Orca Clearinghouse when available and supports dynamic NLR VLANs with other Cluster D sites via Starlight. We demonstrated this at a GEC 7 plenary demonstration and other GEC 8 demonstrations Continuous Experimentation – We support simple web portal access to ViSE’s standalone testbed as well as programmatic access through an Orca site authority (note that RENCI using the programmatic access for VLANs). Our GEC 8 demonstration showed an example of NOWcast experiments. Additionally, we have setup a 4-node Eucalyptus cluster to provide general purpose resources to GENI. Instrumentation and Measurement – Mike Zink attended the I&M workshop and we have contributed documents describing radar sensor data formats (NetCDF) and data flow in ViSE. Interoperability – Our web portal interfaces with an Orca service manager, which is (or will be) capable of supporting a ProtoGENI interface. Identity Management – We have not been active in the identity management space. Our plan is to leverage any updates to identity management in the newest releases of the Orca software.

Sponsored by the National Science Foundation 7 Accomplishments 2: Other Project Accomplishments Educational Benefits – We mentored 2 REU students this summer. One student looked at leveraging existing portal interfaces (e.g., VCL, HybridFox) to provide a better interface to GENI. The other student investigated power monitoring, since ViSE nodes are battery-powered (via solar energy). Outreach – We taught a 3-day class at UPRM on GENI and are continuing our collaboration. UPRM recently finished deploying a radar testbed similar to ViSE. External Publications and Presentations – We had GENI-related publications and presentations at TridentCom 2010, SECON 2010, AAMAS 2010, LANMAN GEC Demos – We conducted an integrated plenary demonstration at GEC7 (with Orca and Starlight). We are planning on a GEC9 integrated demonstration using our NOWcast experiments. Connectivity – We are continuing to work with UMass OIT to increase the number of VLANs we have available for experimenters. Project Support – We frequently respond to mailing list postings by other projects on technical questions related to Orca software. August 6 th, 2010

Sponsored by the National Science Foundation 8 Issues Improve foundation of Cluster D resources –Currently, resources are well-connected but too diverse –Many types of sensors, buses, VLANs, robots, storage,etc. –Better integration with other clusters would help and/or GENI racks –Difficult to get end-to-end users with such diversity Key to increasing user-base is increasing general-purpose resources Future plans –Are there plans for GENI Spiral 1 projects at the end of next year? August 6 th, 2010

Sponsored by the National Science Foundation 9 Plans What are you plans for the remainder of Spiral 2? –Focus primarily on GENI Alpha Demonstration –End-to-end Nowcasting experiments via NLR –Also, integrate our Eucalyptus cluster The GPO is starting to formulate goals for Spiral 3. What are your thoughts regarding potential Spiral 3 work? –Increase level of integration and uptime – Improve the uptime of the RENCI Clearinghouse and the availability of the testbeds. –Increase the Cluster D Foundation – Add a 5 node Eucalyptus cluster to the Cluster D foundation of general-purpose resources. Discuss increasing the number of VLANs available out of UMass. DiCloud resources should also help. Further, the ability for Orca to use ProtoGENI or PL resources or vice-versa would also be a viable option. –Increase the user-base – Increasing the number of general-purpose resources and the number of VLANs should increase the potential for a broader set of end-users (e.g., not just those interested in radar sensing experiments or mobile testbed experiments).
