Rfid-Enabled Inventory Control Optimization: A Proof Of Concept In A Small-To-Medium Retailer, H. Dane, Katina Michael, S. F. Wamba Jan 2010

Rfid-Enabled Inventory Control Optimization: A Proof Of Concept In A Small-To-Medium Retailer, H. Dane, Katina Michael, S. F. Wamba

This study examines the impact of radio-frequency identification (RFID) technology on the inventory control practices of a small-to-medium retailer using a proof of concept (PoC) approach. The exploratory study was conducted using a single case study of a hardware retailer stocking 5000 product lines provided by 110 active suppliers. To analyze the present mode of operation, procedural documents, semi-structured interviews and a participant observation was conducted. The basis for the proof of concept was a future mode of operation using a quasi-experimental design. Results indicate that in a small-to-medium retail environment, RFID technology could act as a loss prevention mechanism, …

Real-World Performance Of Current Proactive Multi-Hop Mesh Protocols, M. Abolhasan, Brett Hagelstein, Jerry Chun-Ping Wang Oct 2009

Real-World Performance Of Current Proactive Multi-Hop Mesh Protocols, M. Abolhasan, Brett Hagelstein, Jerry Chun-Ping Wang

The proliferation of mesh or ad hoc network protocols has lead to a push for protocol standardisation. While there are a number of both open-source and proprietary mesh routing protocols being developed, there is only a small amount of literature available that shows relative strengths and weaknesses of different protocols. This paper investigates the performance of a number of available routing protocols using a real-world testbed. Three routing protocols - Optimised Link State Routing (OLSR), Better Approach To Mobile Ad hoc Network (B.A.T.M.A.N.) and BABEL - were chosen for this study. Our investigations focus on the multi-hopping performance and the …

Digital rights management allows information owners to control the use and dissemination of electronic documents via a machine-readable licence. This paper describes the design and implementation of a system for creating and enforcing licences containing location constraints that can be used to restrict access to sensitive documents to a defined area. Documents can be loaded onto a portable device and used in the approved areas, but cannot be used if the device moves to another area. Our contribution includes a taxonomy for access control in the presence of requests to perform non-instantaneous controlled actions.

From Automatic Identification And Data Capture (Aidc) To “Smart Business Process”: Preparing For A Pilot Integrating Rfid, S. F. Wamba, E. Lefebvre, Y. Bendavid, L.. A. Lefebvre Jan 2008

This paper examines the underlying logic behind the rules configured in a RFID middleware to support “smart business processes” in one retail supply chain. Through a detailed investigation of the underlying business processes, we will demonstrate how businesses rules can be defined, configured and refined in a RFID middleware. The results confirm that RFID technology is not a “Plug and Play” solution. RFID middleware configuration will require a high level of customization. Finally, this study allows the improvement of our understanding of the real potential of RFID technology in the supply chain context.

Embedding Distributed Learning Algorithms In Wireless Ad-Hoc Control Networks, A. Desmet, F. Naghdy, M. Ros Jan 2007

Embedding Distributed Learning Algorithms In Wireless Ad-Hoc Control Networks, A. Desmet, F. Naghdy, M. Ros

With the advances in soft computing techniques and agent technologies, the concept of home ambient intelligence is becoming more and more realistic. Living in a building that adapts itself to the users and assists them in reducing their energy consumption is now within reach. The main technical barrier comes from hardware: servers and industrial control networks do not fit in a house. With the availability of dedicated wireless solutions and low-cost small computation units, the platform to implement task distribution in a control network is now feasible and cost efficient. This paper explores the possibilities of fitting a distributed learning …

Performance Of Java Middleware - Java Rmi, Jaxrpc, And Corba, N. A. B. Gray Jan 2005

Performance Of Java Middleware - Java Rmi, Jaxrpc, And Corba, N. A. B. Gray

Faculty of Informatics - Papers (Archive)

Developers of distributed Java systems can now choose among Java-RMI, CORBA, and Web-Service (JAXRPC) middleware technologies. Performance is one factor that has to be considered in choosing the appropriate technology for a particular application. The results presented in this paper show that the nature of response data has a greater impact on relative performance than has been allowed for in most previous studies. Relative performances of the technologies as measured on simple requests and responses are not representative of the behaviour that can be expected in practical applications.

Near-Distance Software Engineering Education, F. O'Brien Jan 1994

Near-Distance Software Engineering Education, F. O'Brien

Faculty of Informatics - Papers (Archive)

The University of Wollongong has been seeking ways by which it can attract capable students from the southern side of the States capital city, Sydney, Australia. The paper describes the concept of limiting the required daily travel to the University through an amalgam of technologies, and changes to the core teaching syllabus. Progress through 1994, and plans for full introduction in 1995, is described.
