  1. ExScal Breakout Session Summary ExScal Team June 2004

  2. Deployment • numbers (>5 tons of batteries, days of recharge time, etc) • emplacement (> 8 hrs for XSM, Stargates, BaseStation) we seek ways to automate -- reduce these numbers • concerns: • how can we make deployment robust? (planning for slack, breaks, mistakes, accidents) • how can we confirm/validate correct deployment? (signals that XSMs are on, are properly emplaced, & Stargates in network); • how can we estimate power reserves, monitor units degrading during deployment? • dry run will improve deployment processes before December demonstration date

  3. Metrics • Operational: deployment time/effort, cleanup, maintenance cost, ability to activate/sleep-control • Effectiveness: PFA metrics, response time, ability to handle different types of intrusion, visualization, coverage • Performance: routing metrics, synchronization, power consumption metrics, sensing accuracy, localization accuracy, time to reprogram Concerns: do operational/effectiveness metrics relate well enough to application/scenarios? Does software design adequately log/report for desired metrics?

  4. Experiments • The main show: grid, intrusion scenarios (persons entering from beach, vehicles entering from beach, 10k run, etc) • The process for adding experiments to follow demo: • Submit “Experimentation/Demonstration Proposal” (no later than 9/15) to DARPA and OSU for approval. Should include: • Purpose and Objectives • Development Schedule • Integration and Test Plan • Experimentation/Demonstration Requirements (e.g., special equipment, support personnel) • DARPA and OSU will coordinate to schedule experiments. • OSU will make available API for invoking ExScal services

  5. Suggestions for Experiments • MIT: goal: observations leading to {localization,synchronization,calibration,…} • MITRE: Measuring acoustics of aircraft • VU: Long-path routing without Stargates • PARC: local, mobile queries by laptop • UCB: RSSI; SNMS; multiple object tracking (grouping, ungrouping of intruders); routing experiments • ARL: Try different sensor patterns (emulate real dispersion) • Degradation testing (saturating bandwidth, probing for weaknesses in architecture, stress testing)

  6. Packaging • XSM package concerns (protection from rain, ability to replace batteries, acoustic & PIR requirements) • Boxing/packaging for deployment 41 sensors in 1ft cube box, 20lbs. stargate batteries, antennas, GPS tools for placement

  7. Timeline Concerns • would like to set up invitations by 8/31, but XSMs not arriving until end August • About 15 XSMv2s in [July 15 – Aug 30] period: can we learn enough? • 1000 node test 10/30/04 --- weather, terrain
