Computer Sciences Seminar Design and Performance Modeling of Wireless Networks
Benyuan Liu Abstract Mobile and wireless networks have undergone tremendous growth in the past few years. Many new applications and services have started to emerge. These technologies have significantly transformed many aspects of our society and everyday life. The growth is expected to continue for the years to come. The inherent characteristics of mobile and wireless networks, such as limited bandwidth and battery power, dynamic topology, error-prone channels, pose great challenges to the performance of wireless networks. This talk will summarize my work on characterizing and improving the performance of wireless networks. In this talk, we will first study the data transport capacity of wireless ad hoc networks, which is a fundamental measure of the amount of information that a network can carry. Next, we will study the reliable data transport in wireless networks. We propose a cross-layering approach that significantly improves TCP performance in wireless networks. Last, we will investigate the performance of wireless sensor networks, more specifically, the coverage and detectability of large-scale sensor networks. Bio |
