Abstract(in Japanese) (See Japanese page)
Abstract(in English) Mobile networks have been expanding and IMT-2000 further increases their available bandwidth over wireless links. However, TCP, which is a reliable end-to-end transport protocol, is tuned to perform well in wired networks where bit error rates are very low and packet loss occurs mostly because of congestion. Although TCP sender can execute flow control to utilize as much available bandwidth as possible in wired networks, there is the posibility that it cannot execute flow control effectively in wireless networks characterized by high bit error rates because of changing the link bandwidth and/or the transmission delay time due to air conditions. Therefore, in this research, we will focus some information on wireless link conditions which can be obtained from Layer 2 at the mobile station, and propose the receiver based TOP flow control using the information. We investigate the performance of proposed TCP in wireless networks by means of simulations and show that the receiver based TCP flow control can moderate the performance degradation under the condition that FER on Layer 2 is high.
