Cellular-based Machine-Type Communication (MTC) will become more and more important in the near future for the advantage of the long-distance wireless communication.However,a large number of MTC applications introduce heavy load to cellular network.MTC traffic scheduling schemes are proposed to avoid congestion in this paper.Our approaches are based on the delay-tolerance of MTC traffic.Some MTC traffic is postponed until the network load becomes light.Moreover,our scheme efficiently utilizes the bandwidth resources reserved for handover in traditional cellular network.Simulation results show that the utility usage of radio resources is improved and the congestion probability is reduced.
Cellular-based Machine-Type Communication (MTC) will become more and more important in the near future for the advantage of the long-distance wireless communication. Having, a large number of MTC applications introduce heavy load to cellular network. We propose to avoid congestion in this paper. Our approaches are based on the delay-tolerance of MTC traffic. MTC traffic is postponed until the network load becomes light. Moreover, our scheme efficiently profits the bandwidth resources reserved for handover in traditional cellular network . Simulation results show that the utility usage of radio resources is improved and the congestion probability is reduced.
