A radio resource scheduling scheme for periodic M2M communications in cellular networks

Massive machine-to-machine (M2M) communication terminals can cause great challenges in cellular network. One of the critical challenges is to reduce network congestion and control signaling overhead. Most of data types in M2M communication is periodic data, which enables M2M user repetitively access networks, and inevitably lead to network congestion and large control signaling overhead. In this paper, a novel radio resource scheduling scheme which relies on the novel resource multiplexing condition tree (MCT) structure is presented for the periodic cellular M2M communications. Also the resource planning and traffic shaping aspects of this scheduling algorithm are studied. Compared with several different resource scheduling schemes, numerical results show that the proposed MCT based resource scheduling scheme not only can greatly reduce the network access conflict and control signaling overhead, but also yield significantly more efficient time-frequency resource utilization.
