Baseline Application Description:

Street-Smart is an innovative implementation of the GPS (Global Positioning System). It is a navigation utility that enables the user to find directions to his/her destination quickly and efficiently.

For our examples, we will use some information of the Shadyside neighborhood:

New in the city? Don’t know how to reach your destination? Are you lost? Now there is no need to worry, simply use Street Smart:

· While in your car (client), simply turn the Street-Smart device on and send us your destination address.

· The Street-Smart satellites will identify your location along with your car ID number and relay it back to the Street-Smart server.

· The server will then calculate the shortest path from your current address to your destination and send this information back to you.

· If you take a wrong turn, don’t worry. Since Street-Smart is constantly guiding you (as long as the Street-Smart device is kept activated in your car), it will recalculate the path using your current location and redirect you accordingly.

A more detailed outline of the project can be found in the appendix (in the form of use cases).

Configuration:

· Front-end: Java Swing (GUI)

· Operating System: Multi-platform

· Middleware: EJB

· Language: J2SE (on client), J2EE (on server)

Third Party Software:

· EJB Container: JBoss

· Database: MySQL

Baseline Application Features:

· The client (driver) will turn on the Street-Smart device in the car in order to establish a connection.

· This device, when turned off will end the connection.

· The client will send the desired destination street name to Street-Smart.

· Street-Smart will send the directions (the following street name in the path) back to the client.

· Street-Smart will send additional information in the direction (whether to turn left or right on the following street) (optional).

Reliability Requirements:

· If one GPS Server crashes, it will restart automatically.

· If one GPS Server crashes, another server will take over within 5 seconds of its occurrence.

· After the crash, the server will reboot itself and become active (with up-to-date information) within 60 seconds.

Real-Time Requirements:

· Street-Smart will support up to 420 (estimate) concurrent clients.

· While connected, the client will receive up-to-date information within a 5-second latency.

Performance Requirement:

· After turned on, the client will receive the position information in approx 10 seconds

· The client will get the latest information about the position and direction in approx every 3 seconds continuously

· Each time the client query about the position information, he/she will get the information in 5 seconds.
