Estimation of the Efficiency of Bandwidth Request Piggybacking to Data Packets in the Wireless Network Controlled by the IEEE 802.16 Protocol

摘要

A data transmission process of the centralized wireless network controlled by IEEE 802.16 protocol, in which a set of subscriber stations utilizes the common channel to transmit data to the base station, is discussed. The developed analytical model makes it possible to investigate the efficiency of upstream traffic transmission, including channel reservation using the random multiple access algorithm and packet sending with allowance for bandwidth request piggybacking onto data. The analytical estimates of packet registration and service durations are presented.
