ANNOUNCEMENT – COE MS THESIS DEFENSE

Mr. Muhammed Naseer Bajwa, Full-Time COE MS Student, will defend his MS Thesis on Thursday, December 04, 2014 at 03:00 p.m. in 22-119. His MS thesis title is “WIRELESS DISTRIBUTED MONITORING AND CONTROL FOR RECONFIGURABLE PRODUCTION LINES USING RTPS BASED MIDDLEWARE ”. His Thesis Advisor is Dr. Basem Al-Madani, Asst. Professor, COE Department. You are cordially invited to attend.

Abstract: Reconfigurable Manufacturing Systems (RMS) are rapidly becoming choice of production and manufacturing industry due to their quick adaptability to the ever-changing market demands while maintaining the quality and cost of the products. Such RMS are usually decentralized in their monitoring and control and consist of heterogeneous components. Therefore, need arises for an interface that can mask the heterogeneity and provide smooth communication among these dissimilar components. Data Distribution Service (DDS) is a data-centric middleware standard based on Real-Time Publish/Subscribe (RTPS) protocol that fulfils the job of such interface in distributed systems. In this work we are presenting the idea of using DDS-based middleware over commonly used wireless channels like Bluetooth and Industrial WiFi to facilitate data communication in distributed control systems. A simulation model is developed to quantify various performance measures like Latency, Jitter, and Throughput and examine the suitability of aforementioned wireless channels in distributed monitoring and control environments. The model explores various communication scenarios based upon a practical case study. Obtained results serve as an empirical proof of concept that DDS can ensure reliable and timely data communication in firm real-time distributed control systems over common wireless channels and offer extensive control over various aspects of data transmission through its rich set of QoS policies.

Refreshment (Tea, cold drink, water and cakes) will be served
