In the machine-to-machine multilayer heterogeneous network, the data produced by a machine can be constel ated to data aggregators and connected to the infrastructure network and cloud terminal. This can provide the intel igence information service based on the Internet of Things to the users. In this paper, our mathematical analysis provides general analytical closed-form end-to-end delay of HetNet, the model of multilayer heterogeneous network. The results show that by the arrangement of the high-efficiency data aggregator, the information can be sent from machine to cloud terminal and greatly reduce average delay. It also provides strong support for the design of multilayer heterogeneous network of wireless network service provider of next generation.
