On Radio Resource Allocation Scheme Model with Fixed Transmission Zone for Heterogeneous M2M Traffic in LTE Network

Today human is surrounded by many technological devices (sensors, smartmeters, etc.) that become connected and will reshape the Internet as we know it today. These devices can transmit and receive data through wireless interfaces transmitting data independently and automatically, thereby generating M2M (Machine-to-Machine) traffic. Efficient service of M2M traffic remains a challenge for future mobile networks. Such massive connectivity offers novel attractive services and provides additional income for operators, but also raises significant challenges to manage large number of devices, typically transmitting only small data fragments. This is especially true for LTE (Long Term Evolution), which has been historically optimized for H2H users (Human-to-Human). Consequently, it is required to develop new methods for M2M traffic for each phase - from the connection establishment phase to the data transmission phase. The article proposes a scheme of dynamic radio resource allocation of LTE cell with fixed transmission zone for heterogeneous M2M traffic. The stationary probability distribution is obtained and the numerical analysis is performed.
