Machine-type communication (MTC) networks face the challenges of massive access and diverse quality of service (QoS) requirements. In this paper, we focus on satisfying various QoS requirements for massive number of MTC devices. By dividing these devices into multiple clusters based on their QoS characteristics, we formulate an access control problem to maximize the access efficiency while satisfying both the access and transmission delay requirements. An efficient algorithm is proposed to solve the problem by adaptively adjusting the access time intervals and back-off factors of the clusters. Simulation results show that the proposed scheme outperforms other schemes in terms of access efficiency. The impacts of various parameters including delay and traffic rate on the performance are disclosed.
