Autonomous Data Transmission Using Off-Peak Hours for Cellular-Based M2M Communications

This paper proposes autonomous data transmission using off-peak hours for cellular-based machine-to-machine (M2M) communications. In the near future, there will be an enormous number of machine type terminals (MTs) capable of connecting to cellular networks. Thus, an efficient scheme for accommodating M2M traffic in existing cellular networks is required. To tackle this challenge, we focus on the fact that there are a lot of delay-insensitive services in M2M communications. The goal of the proposed method is to shift such traffic to off-peak hours in a scalable, flexible and simple manner. We evaluate the proposed method through a field experiment and a computer simulation using traffic data obtained from a commercial cellular network.
