WQM: Practical, Adaptive, and Lightweight Wireless Queue Management System
In today's Internet, real time applications are extremely sensitive to latency. One of the causes of latency is the long queuing delays which is a natural consequence of over buffering. With the falling costs of memory and the fallacy that "more is better", network devices are being over provisioned with large buffers. On the other hand, under-buffering leads to frequent packet loss and subsequent under-utilization of network resources. In this talk, buffer sizing challenges in wireless networks will be presented along with two novel buffer sizing schemes. The first scheme targets buffer sizing in wireless multihop (mesh) networks where the radio spectral resource is shared among a set of contending wireless routers. The second scheme is designed to utilize various IEEE 802.11n/ac enhancements, such as frame aggregation. It adapts the buffer size based on measured link characteristics and network load. I will also highlight the relevant work done at the Netlab group in KAUST.
Basem Shihada is an assistant professor in the Computer, Electrical and Mathematical Sciences & Engineering (CEMSE) Division at King Abdullah University of Science and Technology (KAUST). Before joining KAUST in 2008, he was a visiting faculty at the Computer Science Department in Stanford University. In 2007, he held a research associate position in the Department of Electrical and Computer Engineering at the University of Waterloo. His current research covers a range of topics in energy and resource allocation in wired and wireless communication networks, including wireless mesh, wireless sensor, multimedia, and optical networks. He is also interested in network security and cloud computing. In 2012, he was elevated to the rank of Senior Member of IEEE.
