SAL-I PROJECT FINAL PRESENTATIONProject Summary of the Web-based GUI for SAL

Overview The SAL-I project team

Marc Hammerton Jörg Seifert Xu Du Scott Messner

The overall objective was to develop a graphical user Interface for SAL.

What is SAL? Sensor Abstraction Layer (SAL)

interfacing tool for managing large networks of sensors.

Multiple, unique devices one uniform system.

Command-line interface Textual data only

Different sensors

Command-line interface

SAL Agent

SAL-I is a web-based user interface to SAL Graphical representation of raw data. Remote access from anywhere. Increased user acceptance.

Main Components:

SAL-I

ApplicationServer

WebInterface

What is SAL-I?

SAL Agent

Requirements Achieved General

Web-based Dynamic Operating System Information Web Service Interface

Support of Multiple Sensor Types i-Wire (temperature sensors, pressure sensors,

etc.) JPEG/V4L (web cams, etc.) SMNP (collection sensors)

Requirements Achieved (continued…) SAL interaction:

Display of SAL Information List of sensors List of commands for a sensor Sensor output List of protocols Display OS Information

Managing SAL Add/remove a sensor Add/remove a protocol

Piloting Sensors: Send commands to a sensor Change sensor configurations

Problems/Obstacles Team

Communication Knowledge

Technical Performance

Web Service Interface cancelled Cache implemented

Environment RMI/Application Server configuration Project configurations

Video/Image Display Raw data conversion Javascript limitations GWT limitations

Conclusions Project Result

Nearly all requirements fulfilled Client is satisfied with outcome

Project Management More difficult than expected Strong start and finish, weak transition

Final Statement: Minor setbacks but overall success!
