An Optimal Service Strategy for Grouped Machine-Type Communications in Cellular Networks
Machine-type communication devices (MTCDs) served as groups are an efficient way to solve device management and resource allocation problems in cellular networks. We propose an MTCD group model based on the traffic of devices in the network. A group state transition matrix and revenue and constraint vectors are introduced and the optimal service solution is derived that the best service strategy is to serve devices in only two groups. Results can be used as a guide for cellular base stations to efficiently manage resources for MTCD applications.
