  1. Overview of the Generic Sensor Kit (GSK) Wei Hong whong@intel-research.net January 16, 2003

  2. Outline • Goals • Usage Model and Tool Set • Architecture • Description of components • Status and Future Work • Sneak Preview

  3. Overall Goals • Provide an end-to-end software suite for rapid sensor network deployment • Break down the barrier to entry to sensor network applications for non-computer sophisticated users: biologists, vineyard managers, facility managers, civil engineers, etc. … • Integrate and drive our research

  4. Immediate Goals • No Mote programming or code downloading • Focus on data collection applications • Single integrated package with minimal configuration • Easy integration with popular data analysis tools • Scale: up to 100 nodes • Longevity: 6 months at 1-2% duty cycle

  5. GSK Usage Model • Deploy pre-programmed sensor nodes  Deployment Tool • Configure data collection criteria  Configuration Tool • Collect sensor data and monitor network statistics  Logging to DBMS • Visualize and analyze sensor data and network data  NW Monitoring Tool, External Tool • Diagnose problems and refine data collection criteria and network configuration  Diagnostics Tool

  6. Config Log Mote Registry Sensor Data Calib. Data Deployment Configuration NW Stats GSK Architecture Single-patch Sensor Network DBMS Basestation GSK Server JDBC GSK Field Tools JDBC/ODBC Excel Internet GIS GSK Client Tools MATLAB Data Display NW Monitor

  7. GSK Mote Side Components Tiny DB Diagnostics Tiny Schema: Attributes and Commands Multi-hop routing Watchdog EEPROM FS Time Sync. Abs. Timer TinyOS Core

  8. GSK Server • Provide (Java) API to all client tools • Inject queries and commands into sensor network • Deliver live data from sensor network and to interested clients • Log all data, queries and commands to DBMS • Metadata management • Mote locations and maps • Mote capabilities: type of sensors • Mote characteristics: power consumption • Sensor calibration/conversion parameters

  9. GSK Field Tool • Run on a hand-held device • Diagnostics: • Only communicate with motes in radio range • Pull motes out of sleep • Ping a node and collect vital signs • A small number of other commands: reset, buzz, etc. • Deployment • Placing Motes on a map and record locations

  10. GSK Client Tools • Deployment and Diagnostics • Configuration • Select attributes, filters and aggregates • Set sample rate or network lifetime • Network Monitoring • Visualization of network topology and other health statistics

  11. Current Status • Developed most pieces • Remaining tasks: • Integration between TinyDB, new multi-hop routing, time sync, snooze • More polished GUI • General Availability: early Q1 2003

  12. Future Work • Apps, apps, apps, … no hand holding • Deployment Tool • Network formation advisor • Run on handheld • Data synchronization with DBMS • Web-based Client Tools • Network monitoring triggers and alerts • Unified interface to access live and historical sensor data • Support for heterogeneous sensor networks • Failover of GSKServer and DBMS • Beyond data collections

  13. Demo Time
