A smart city involves big data transmission (BDT) between systems, which increases queue delays and leads to difficulty in enhancing the spectral efficiency. Adaptive modulation is an effective technique for rates systems. However, traditional adaptive approaches are not suitable BDT systems because caused by large amount of transmitted lead evaluating channel quality.
