This thesis presents a novel infrastructure which allows the Web Service-Based Wireless Alarm Monitoring and Data Acquisition System for Pharmaceutical Plants (WAMDAS) to be a more portable, reliable, secure, and robust system. This infrastructure provides a reliable alarm management mechanism and a functionality to have a pool of available web services to respond the requests on time. Likewise, a Windows-based application is provided to configure dynamically all system information and parameters. Furthermore, the handheld device application was improved with a strong security mechanism to access the system, a system usage control, and a redesign of the user interfaces. The results of the experiments show that the system protocols were optimized when using Stored Procedures instead of in-Line SQL Statements and Message Queues instead of TCP/IP Sockets. And the usability evaluation shows a high level of effectiveness and user satisfaction of WAMDAS at the pharmaceutical plant.
