        abstract = {mMTC (massive Machine Type 
Communications) is one of the key components in beyond 5G 
networks for smart manufactures and the fourth industrial 
revolution. Due to the massive connectivity in mMTC, it is vital 
to have an efficient random access protocol. In the paper, we 
propose a new random access technique called the Adaptive 
ACB (A-ACB) to minimize collisions. We show that, in terms of 
successfully resolved probability, the proposed A-ACB always 
outperforms the ACBPC protocol [1] and surpasses the SUCRe 
protocol [2] when the number of collisions per preamble is large. 
In addition, the proposed protocol achieves better fairness than 
the SUCRe but less than the ACBPC. Finally, numerical results 
are provided to demonstrate the effectiveness of the proposed 
random access protocol.}
