Research on decreasing resource consumption in wireless O2O services operation

Most Internet-of-Things(IoT) applications provided by telecommunication carriers take wireless Object-to-object(O2O) model. In practical operation of these O2O services, lots of requirements for channel occupancy become conflicting with limited resource of air interface. This conflict greatly restricts service operation, and hence, blocks the growth and expansion of IoT. The main contribution of this paper is to summarize general O2O service types, and to propose principles of solving resource overspent in air interface. Schemes of avoiding channel collision when many terminals transmit data almost at the same time are also proposed.
