This discovery grant will explore a new scheduling algorithm which can achieve near-perfect Quality of Service (QoS) over general packet-switched networks and infrastructure-based Wireless Mesh Networks (WMNs). The Internet has had an unprecedented impact on society over the last two decades. Compared to other disruptive technologies such as radio, telegraph, telephone, television, and the personal computer, the Internet has had one of the fastest adaptation times to reach the majority of the North American households. The outlook for new services over the Internet is tremendous, and these include telemedicine, telerobotic systems and Intelligent Highway System. However, there are significant unsolved technical problems to be addressed. In 2007, the US National Science Foundation (NSF) has embarked in a new program called 'Global Environment for Network Innovations' (GENI), with the goal of addressing the problems that have 'plagued the Internet' since its inception. These problems include Quality of Service, security, reliability, and the seemless integration of wireless technologies. These problems are so complex that the GENI program is open to a 'clean-slate' approach in which the entire Internet may be re-designed from ground up. This applicant has developed a new scheduling algorithm. The algorithm can achieve near-perfect Quality of Service for statically provisioned multimedia traffic flows in general packet-switched networks such as the Internet, including the wired IP networks and infrastructure-based Wireless Mesh Networks. Funds are requested to explore this algorithm in more depth.
