Project aims


Test the Tracy
mobile agent
system.
Create an
application under
the Tracy
environment which:
– Distributes data
– Collects data
– Filters data
Logical network, over which mobile agents
issued by the workstation opertes to gather data
from databases.

Design of the application
The application mainly
consists in:
 A gateway agent that
interfaces with the
end-user.
 A gateway agent to
bridge the mobile
agent system to
databases.
 2 mobiles agents,
doing the same job but
in a different way.

Implementation


Configuration of Tracy.
Database connection:
– JDBC drivers, ODBC compliant databases.
– SQL queries to filter data.
– Borland containers to store data.

Development of the agents, in Java:
– 2 gateway agents as host interfaces and data
processing.
– 2 mobile agents, with different strategies.

Test of the application and performance of
mobile agents created.
Conclusions



Advantages of mobile agent
technology over traditional high level
networking techniques.
Application distributes, collects and
filters data from databases over a
heterogeneous distributed system.
Application could be used as an API.
