Invited by the High Performance Network Laboratory of IACAS, Prof. Michael Fang from the University of Florida made three lectures on Aug. 13 and 14, ranging from “How to Do Good Research”, "Small World Phenomena in Wireless Ad Hoc Networks” and “Path Capacity in Multirate and Multihop Wireless Networks”.
In the lecture of “How to Do Good Research”, Michael started with how to become a good graduate student, continued with building a research career, and ended up with establishing a good research profession. It was a controversial topic because it was hard to define a good researcher. This topic targeted at advanced undergraduate students or beginning graduate students who were looking for some advices. Based on Michael’s own research experience, he shared what he had learned and what he thought a good researcher should be.
For the lecture of “Small World Phenomena in Wireless Ad Hoc Networks”, small world phenomena had been intensively studied in social networks since the famous Milgram experiment and their studies had also been extended to other types of complex networks. In this talk, the problems in wireless ad hoc networks had been looked into. In particular, how the small world was formed, under what conditions small worlds could be formed and the small world paths could be found using distributed algorithms had been discussed.
"Path Capacity in Multirate and Multihop Wireless Networks” introduced that finding a path with certain throughput in multihop wireless ad hoc networks was a critical and challenging task of QoS Routing. Previous studies on routing algorithms focused on networks with a single-channel rate. The capability of supporting multiple channel rates commonly seen in wireless systems had not been fully utilized in routing algorithms. In this talk, Michael presented his recent study on the impacts of multiple rates, interference and packet loss rate on the path capacity (i.e., the maximum end-to-end throughput) and his solution to the linear programming problem for the path capacity of any given path, leading to the joint routing and link scheduling optimization to find a path with the maximum path capacity. He also demonstrated that the newly introduced interference clique transmission time was the best routing metric in finding the path with high end-to-end throughput.
