题目： Bio-Inspired, Multi-Beam Wireless Airborne Networks with Cross-Layer Transport/Routing Control
Dr. Fei Hu is currently a professor in the Department of Electrical and Computer Engineering at the University of Alabama (main campus), Tuscaloosa, Alabama, USA. He obtained his Ph.D. degrees at Tongji University (Shanghai, China) in the field of Signal Processing (in 1999), and at Clarkson University (New York, USA) in the field of Electrical and Computer Engineering (in 2002). He has published over 200 journal/conference papers, books, and book chapters. . Dr. Hu’s research has been supported by U.S. National Science Foundation (NSF), U.S. Department of Defense (DoD), Cisco, Sprint, and other sources. His research interests are 3S - Security, Signals, Sensors.
In this talk, we target the routing design in a directional hierarchical wireless network that has popular applications in airborne surveillance, smart factory, sensor and actuator systems, etc. Such a network has the following 2 main features: (1) Two-level architecture: The high level is a sparse wireless network with long-distance links and high-rate communications. It also has a commander node that collects data from the entire network and sends control commands. The lower level is a dense network with short-distance low-rate links. (2) Hybrid directional antennas: The network has mixed antennas (multi/uni/omni- directional antennas). Our goal is to build an innovative routing that can (1) fully explore the multi-beam multi-channel links to achieve a high-throughput, GPS-free transmission between long-distance high-level nodes, and (2) in the low-level network, allow any event node to report data to a sink node that could suddenly move away.
