ViSE: Virtualized Sensing Environment

David Irwin, Mike Zink, Prashant ShenoyJim Kurose, and Deepak Ganesan

GENI Spiral 1: Cluster D/Orca


Background

GENI and Sensor Networks: “…in 10 years, most computers…will be

small sensors and actuators…to monitor health, traffic, weather, pollution, science experiments, surveillance, etc.”

“It would seem odd if in 10 years we were still living with an Internet that did not take into account the needs of the majority of the computers then deployed.”


Sensing and Actuators ac-tu-a-tor n. A mechanism that causes a

device to be turned on or off, adjusted or moved. Nearly every device has actuator(s)

E.g., CPUs, NICs, disks, sensors Essence of “deeply programmable”

Actuation key for sensors:

Determines data type, quality, quantity, etc. E.g., Sampling rate, Steering, Power

Indirectly affects resource usage E.g., energy, bandwidth, storage, processing


Broad Range of Sensor Networks

radar/weather

satellite observation(EODIS)

auto traffic monitoring

videosurveillance

vehicle trackingin sensor field

habitat monitoring microclimate

monitoringanimal tracking

network traffic monitoring

underwatersensing

Many differences, but also many commonalities

ViSE Testbed Overview Experiment with Actuation

In addition to slivering CPU, memory, network, etc…. ….goal is to virtualize and sliver sensors

Infrastructure 3 nodes - weatherproof, solar-powered Network - long-distance 802.11b/g Sensors - radar, Weather Station, Camera Backplane - cellular + embedded node

gap

“There is insufficient knowledge about what is actually happening (or is likely to happen) at the Earth’s surface where people live.” [NRC 1998]

Example: Weather Radars


finer spatial resolution

beam focus: more energy into sensed volume

multiple looks: sense volume with most appropriate radars

instead of this….This:

Benefits of Better Actuation

FLUS74 KOUN 102343 AWUOUN

AREA WEATHER UPDATE NATIONAL WEATHER SERVICE NORMAN OK 742 PM CDT TUE APR 10 2007

..WARNING DECISION UPDATE

THIS WARNING DECISION UPDATE CONCERNS COMANCHE AND GRADY COUNTIES.

MESOCYCLONE NEAR STERLING CONTINUES TO STRENGTHEN PER TWO RADAR VIEWS. CASA NETWORK ALSO SHOWING PRONOUNCED HOOK. STORM WILL ENCOUNTER WARM FRONT...WITH POSSIBLE ENHANCED LOW LEVEL SHEAR JUST EAST OF STERLING AND WEST OF RUSH SPRINGS. TORNADO WARNING IS POSSIBLE IF NOT LIKELY TO BE ISSUED AS STORM REACHES SOUTHWEST GRADY COUNTY.

Orca: Cluster D Vise Focus:

Physical Infrastructure Virtualized Actuators (Xen) Orca Integration

New VM/Slivering Mechanisms

Augmented Policies Publicly-available Testbed


Integration Plans ViSE is a self-contained testbed

Federate through Orca clearinghouse Some interaction with other Cluster D projects

New slivering mechanisms/policies Integrate into Orca framework

Experiment/portal services Slice controllers, Gush (Williams)

Interfaces Experiment/Data Plane: virtual sensor interface Control Plane: GENI/Orca Operations & Management: GENI/Orca


Timeline: Year 1

Demo - GEC4 (~March ‘09) Infrastructure deployed and

operational Reflectivity Overlay using Google Maps

Initial Orca Integration Web portal; request slices of Xen VMs

Demo - GEC5 (~July ‘09) End-to-end slices across ViSE and
