  1. 1. Low Power Wireless Ad Hoc Sensing Nets:  Netted micro laser radars (MLRmotes), infrared motes (PIRMotes) Low-power, Worldwide relay capability (SERI)

  3. 3. Low-power, wireless, netted sensors -- The Problems <ul><ul><li>Significant advances were accomplished in distributed processing of netted sensors, however, mote-based sensors were severely lacking: </li></ul></ul><ul><ul><ul><li>Produced excessive false alarm rates </li></ul></ul></ul><ul><ul><ul><li>Provided low probability of detection, </li></ul></ul></ul><ul><ul><ul><li>Exhibited ineffective detection ranges (<10m) </li></ul></ul></ul><ul><ul><ul><li>RF range ~ 20-30m (on the ground); indicate netted mote period ~ 10m </li></ul></ul></ul><ul><ul><li>Numerous systems issues included: </li></ul></ul><ul><ul><ul><li>Random processor performance </li></ul></ul></ul><ul><ul><ul><li>Low battery life </li></ul></ul></ul><ul><ul><ul><li>Extremely difficult to maintain (no fabrication/design feasibility) </li></ul></ul></ul><ul><ul><li>RF emissions that would jam, or interfere, with field operation. </li></ul></ul><ul><ul><li>Mote designs not consistent to that required by end-users, and could not be modified to accommodate such demands. </li></ul></ul>
  4. 4. <ul><ul><li>Use of active optics (micro solid-state laser radar) </li></ul></ul><ul><ul><ul><li>High Pd </li></ul></ul></ul><ul><ul><ul><li>Low FAR sensor (require target characterization to discern target types) </li></ul></ul></ul><ul><ul><ul><li>Significant operational range (100-1000m) </li></ul></ul></ul><ul><ul><li>Address power use </li></ul></ul><ul><ul><ul><li>Sensor X </li></ul></ul></ul><ul><ul><ul><li>Nearest-neighbor field processing to provide detection/trigger criteria </li></ul></ul></ul><ul><ul><ul><li>Solar recharging circuit (polysilicate solar array) </li></ul></ul></ul><ul><ul><ul><li>Coordinate with effective relay structure (SERI) </li></ul></ul></ul>1 Low-power, wireless, netted sensors -- A Solution: MLRmote and PIRmotes intercalated field Randomly dispersed and oriented motes detect traversing objects within the area of interest.    The capability to provide high Pd, with minimal FAR, and support ranges ~0.1-1 km per unit provides a formidable low cost, low power capabilty. PIRmote MLRmote
  5. 5. Effective sensor data exfiltration & commanding-- The Problems <ul><ul><li>The Issues: </li></ul></ul><ul><ul><ul><li>Scalability quickly overwhelmed relay technologies build to work with mote fields (throughput handling capability overwhelmed by message traffic) </li></ul></ul></ul><ul><ul><ul><li>Relay-to-relay communications were not considered and/or realized in mote-field environment (R2R allows for data/command transport sharing) </li></ul></ul></ul><ul><ul><ul><li>Adaptive exfiltration schemes not addressed, including use of worldwide communications architecture such as GSM, which provides multi-level security, broadcast (1-to-M) capability, redundancy (ref. AT&T) </li></ul></ul></ul><ul><ul><ul><li>In-field processing minimal (relay capability can support data processing and/or compression) </li></ul></ul></ul><ul><ul><ul><li>PULSENet compatible (OGC compliant) </li></ul></ul></ul>
  6. 6. Effective sensor data exfiltration & commanding <ul><ul><li>Provided direct connectivity to in-field participants </li></ul></ul><ul><ul><ul><li>GSM exfil directed to preplanned cell accounts -> Smartphone provided real-time health/status information </li></ul></ul></ul><ul><ul><ul><li>Worldwide support in place </li></ul></ul></ul><ul><ul><ul><li>Expandable using 1:M broadcast (supports R2R link) </li></ul></ul></ul><ul><ul><li>Supports adaptability for L-band (previous exfil) and GSM </li></ul></ul><ul><ul><li>Allows for in-field processing expansion </li></ul></ul><ul><ul><li>Supported imager activity based on relay/field queuing </li></ul></ul>GSM Cell Module Switched Ext. Battery Header (P5) Cell Antenna Lithium-Ion Battery CMOS Camera Tmote Mini 2.4GHz SMA Antenna Connector Power Switch Regulator I/O Header (P4) JTAG Header (P3) RS232 Header (P2) STR 711F ARM Microcontroller
  7. 7. ARMMIC Performing localization when GPS is absent &  providing volumetric measurements on-the-fly
  8. 8. ARMMIC, Micro-Scanning Volumetric (3D) Laser Radar -- Problems Addressed <ul><ul><li>Objectives associated with a military, civil, security -- a detailed “map” of a structure, or area-of-interest, especially those enclosed or underground, become the first order. </li></ul></ul><ul><ul><li>ARMMIC provides a GPS capability where GPS is non-existent. </li></ul></ul><ul><ul><ul><li>Military applications -- pursuit of persistent intelligence, surveillance and reconnaissance (ISR) require location of targets detected and/or tracked. </li></ul></ul></ul><ul><ul><ul><li>Mine operators -- required constant communication and maintain constant position data on all personnel available to those above ground. </li></ul></ul></ul><ul><ul><ul><li>Fire fighters -- working in a complex building under fire conditions need to know where they are regardless of smoke or obscurants. </li></ul></ul></ul><ul><ul><ul><li>Security - understanding how an area, or volume, has been altered from that originally built or planned might indicate a security weakness or an area that might be of &quot;concern&quot;, such as “hidden” compartments. </li></ul></ul></ul>
  9. 9. ARMMIC Initial Capabilities Demonstration:  volumetric measurements in near real-time Note penetration of baffles, vents, fixtures indicate drop ceiling & “real” (concrete) ceiling Scans of small conference room showing operator (baseball capped), and associated “shadow”. Scanner origin
  10. 10. ARMMIC Initial Capabilities Demonstration: volumetric measurements 12 x 12 x 12 ft 3 in 60 seconds Scanner origin Note subtle structures as tile rails, baffled lighting, and dropped projector Total time duration for scan was 65-70 seconds at resolution (1-degree). A reduced data set option exists; allows for estimated volume (3D box) drawing ; a flattened, 2D output is optional).
