Embodying Link-Quality Awareness for QoS-Adaptive Multi-Hop Wireless Networks
With the ever increasing demands for ubiquitous Internet access, multi-hop wireless networks have shown a great promise for extending the Internet territory closer to mobile end-users. For example, city-wide wireless mesh networks, wireless back-haul networks, and disaster monitoring systems have been actively developed and widely deployed in many cities across a number of countries. However, due to the error-prone nature of wireless links, multi-hop wireless networks often suffer poor network Quality-of-Service (QoS) and/or incur expensive management costs, hindering the deployment and acceptance of such networks.
In this talk, I will first overview the importance of link-quality awareness for facilitating QoS and manageability in multi-hop wireless networks. Next, I will present an efficient and accurate link-quality monitoring framework (EAR) that essentially embodies link-quality awareness for multi-hop networks. Finally, I will present two link-quality adaptation frameworks (LEGO and SMART) that are built upon EAR and that enhance network QoS and manageability through multi-channel diversity and robot-based spatial diversity, respectively.
Biography
Kyu-Han Kim is currently a Ph.D. candidate in the Department of Electrical Engineering and Computer Science, at The University of Michigan, Ann Arbor. He received his M.S. degree from Georgia Institute of Technology in 2003 and B.S. degree from Korea University in 2000, both in Computer Science. His research interests include wireless networks, distributed/embedded systems with emphasis on Quality-of-Service and fault-tolerance. He has published research papers in prestigious international conferences and journals, including ACM MobiCom'03, MobiSys'05, MobiCom'06, MobiCom'07, IEEE Transaction on Mobile Computing (TMC), and ACM Wireless Networks Journal (WINET). He is a recipient of the student best paper award from MobiCom'03 as well as the advanced study scholarship from the Ministry of Information and Communication, Republic of Korea.
