The rapid growth of high-speed transit systems, such as High Speed Rail (HSR), is putting considerable pressure on TCP-based data transmission. It is well known that TCP is suffering from severe throughput degradation in high-speed mobility scenarios. The root cause at the transport layer however remains unclear and largely undetermined to date. In this paper, we aim to pinpoint the throughput bottlenecks...
There are many performance issues concerned in a semiconductor wafer fabrication facility (fab), such as move, queue length, utility, cycle time, throughput and on-time delivery rate. However, it is difficult to demonstrate their relations to each other. In this paper, the correlation coefficient method is utilized to analyze their relations from plentiful simulation results and obtain some meaningful...
In this paper, we consider cooperative ad hoc networks and develop an analytical model to study the performance of reliable relaying schemes. In particular, we develop expressions for throughput rate and spectral efficiency for cooperating radios in a fading environment. The numerical results indicate a performance conflict between throughput rate and spectral efficiency, which depends on the underlying...
