The document details the Geodise project's use of SMS technology for two-way communication in grid computing environments, allowing users to send notifications and retrieve replies via mobile devices. It describes system architecture, design, and tools that facilitate interactions between users and servers, including MATLAB functions like gd_sendtext and gd_sendmail. Future work aims to enhance communication by enabling replies from mobile devices to the messenger server and improving data queries within the system.

Aims
• Using SMS in Grid environment
• Two-way communication
 Send notifications to a mobile user
 Retrieve the replied message from the mobile user to perform a certain
task
 Relieve users from being bound to their desktops
• Using SMTP to send images and large files
• Be able to be plugged-n-played in any Grid-enabled
environment

Using gd_sendtext in Matlab
Type gd_sendtext(‘00447880707831’, ‘job done,
results send to webmaster@geodise.org’) in
Matlab environment as shown below
 Check if the user has a valid proxy certificate
 Create a proxy if there is no valid one
 Submit a job to Globus Server
 Start the Messenger Application
 Send the message to the Messenger Server
 Receive the message from the mobile phone

Using gd_sendmail in Matlab
gd_sendmail(‘Hakki.Eres@soton.ac.uk’,
'Simulation results from Geodise 0.3.3 demonstrator',...
'A short report and a pressure contour plot is attached',
{'report.txt','pressure.jpg'})

Future Work
• Implement the other way communication
• Send a replied message from mobile phone to
the messenger server
• Update the entry in the database
• Query the entry from the application in Matlab
