CatchBob! Visualizer

Posted: August 10th, 2004 | Comments Off

CatchBob! Visualizer is built on top of the CatchBob! Server. It visualizes real-time, recorded or simulated activities of the CatchBob! players. Its goal is to provide a base to analyze the wide load of data generated during a game.

Current features:
Real-time:
- Start/Stop a CatchBob! Server
- Store into a .log file the game events (command and refresh)
- Play with virtual players

Replay:
- Load games .log file and replay all the game events
- Forward, rewind, skip

Simulate:
- Base to simulate with agents and have “smart” virtual players

View:
- History
- Commands
- Triangle
- Time
- Logs
- Path length

Future directions could be:
- Visualize what every player experiences (view according to the player’s refreshes)
- Global visualization with the movement done outside of the refreshes (using access points sniffed every 7 seconds on the iPaq)
- Easy access to data for statistics and maps generationof the refreshes, commands, triangles, wi-fi usage, % of the campus covered, number of areas each participant searched in, number of areas all the participant searched, overlap, backtracking
- …

Delay between Scanning and Listing Access Points

Posted: August 4th, 2004 | Comments Off

Funny to see the people at Placelab stumbling on the same problems as me. From their mailing-list:

Originally, our xp spotter sends the scan command to the NDIS driver, than it immediately queries the driver for the bssid list. However the scanning happens at background and the scan function returns immediately (or asychronously). As a result, the bssids returned is in fact for the second to the last scanning. EX: If we are scanning at 2 second interval, the bssids returned were 2 second old. A quick fix is to simply wait certain time after the scan command. MSDN suggest 6 seconds, but I use 300 ms based on the Linux spotter setting.
