Welcome to WiSPER Group

The Wireless Systems and Performance Engineering Research (WiSPER) group at The Center for Advanced Computer Studies, University of Louisiana undertakes basic and applied research on various aspects of wireless networking systems, centered on three inter-related themes:

  1. Cross-layer Protocol Design. This work focuses primarily on protocol design and efficient cross-layer data sharing frameworks for large-scale multi-hop wireless networking systems, including mobile ad hoc networks, broadband mesh and relay networks, sensor wireless networks, and cognitive radio-based networks. Our ongoing design work spans several specific topics including, cooperative diversity-based relaying, medium access control, multi-path routing, fast handoff, localization, reliable transport, resource management, probabilistic spectrum sharing, and routing-aware spectrum management.


  2. Application Specific Design and Prototyping. Our aim here is to develop fundamental scientific principles which guide the engineering of large-scale integrated multi-hop wireless monitoring and communication systems for applications spanning emergency/disaster recovery, human and building health monitoring, and oil and gas resource discovery and management.


  3. System-level Performance Engineering and Management. Performance engineering work is concerned with i) analyzing the utilization of wireless system resources and characterizing the performance (e.g., delay, throughput, and loss rates) of multi-hop wireless networks under various deployment scenarios and environmental conditions; ii) engineering distributed protocols and algorithms capable of satisfying specific application QoS demands; and iii) designing, implementing, and deploying autonomic performance management systems capable of efficiently monitoring the performance of multi-hop wireless systems and responding appropriately with little to no human intervention. Using both analytical and empirical modeling, performance estimation approaches, and control theory principles, our performance analysis work guides the protocol design and prototyping efforts.

The WiSPER group aims to create an interactive, collaborative, and stimulating environment, promoting fundamental research exploration, technical innovation, ingenuity, and entrepreneurship in wireless networking and communications. We actively pursue and promote cross-disciplinary and industry partnerships and collaborations. We seek to serve our academic and industry collaborators by creating and disseminating knowledge about wireless networks and communications through research, teaching and technology transfer. Moreover, the WiSPER group has great interests in and welcomes collaborations with faculty and students from non-PhD granting computer science and engineering departments.

The WiSPER group was founded in 2003 by Dr. Dmitri Perkins. Dr. Perkins received his B.S. degree in Computer Science in 1995 from the Tuskegee University and his M.S. and Ph.D. degrees in Computer Science from Michigan State University in 1997 and 2002, respectively. He is currently an Associate Professor at The Center for Advanced Computer Studies (CACS), University of Louisiana at Lafayette. His primary research interests include performance analysis, scalable protocol design, resource allocation, and self-management issues in multi-hop wireless broadband networks, sensor ad hoc networks, multi-hop cognitive radio networks, and the science and engineering of integrated wireless monitoring and communications systems for health and disaster applications. Dr. Perkins received the NSF CAREER Award in 2005 and was awarded the Hardy Edmiston Endowed Professorship in 2008.
