Abstract
Due to the random access (RA) process, machine-type communication (MTC) devices of a group may delay until the time point of the next polling of another groups and lead to a serious access delay problem. To solve this problem, in this paper, we investigate a dynamic backoff indicator (BI) assignment (DBA) algorithm that lets the delayed MTC devices speed up to finish their RA within an expected period of time. The proposed method also realizes the crucial concept of cyber-physical systems (CPS). Simulation results and analyses validate the effects of CPS on reducing collision probability in large-scale MTC.
