Communication control protocol corresponding to quality change of communication line

Wireless communication line such as satellite communication line and wireless LAN has such property as its communication quality changes frequently. On the other hand wired communication line provides stable communication quality. The traditional communication control procedure has been premised on wired communication line. Therefore it is difficult that the traditional procedure controls wireless communication line effectively. In this paper, we propose communication control protocol corresponding to quality change of a communication line. First, we formulate and analyze communication time. We make clear the property of each parameter to control data communication. Second, we introduce our new communication control protocol. Finally, we evaluate the communication time on the parasatellite communication line and discuss relation among quality of communication line, communication condition and communication time.
