METHOD FOR EFFICIENT UTILIZATION OF BANDWIDTH BY DYNAMICALLY VARIED REQUEST PERIOD IN RESERVATION BASED MAC

摘要

The present invention is directed to increase or decrease the length of the requested segment by the retransmission count for efficient use of the bandwidth.; Performance enhancement method through the dynamic adjustment of the request interval length in the medium access control of the reservation system of the present invention dynamically adjusts the request interval length in the medium access control of the reservation system that is configured to include a beacon period, a request interval, the assignment period in the performance improvement method by a first step of the master is informed of the positions and lengths of the request period and the assignment period from the beacon to the slave; A second step of the slave sends a request packet containing the retransmission count and a time slot request for the information request to the master section; A third step of the slave is determined whether to transmit the request packet to the master; Request section in the fourth step and the reservation system a media access control, characterized by the master is made of an a fifth step of determining whether to reduce the length of the request interval in which the master determines whether to increase the length of the requested segment length yirueojim the dynamic adjustment of the performance improvement by way has a technical feature.; Accordingly, the performance enhancement method is network conditions the length of the contention access period to send the retransmission count to the master in the form of the request packet with a time slot request information through the dynamic adjustment of the request interval length in the medium access control of the reservation method of the present invention; while by the slave is adjusted to maintain the amount of time it takes to receive an assigned time slot from the master within a certain level, the effect of preventing the waste of bandwidth that results from the length of the request interval more than necessary.
