Embodiment Construction

[0037] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] According to the energy optimization-based M2M communication joint clustering and resource allocation method described in the present invention, it is assumed that in a cellular network where the intra-cluster communication mode and the cellular communication mode coexist, between two different access modes, and the same The access mode adopts the orthogonal multiple access method, so there is no interference in information transmission; there are multiple M2M devices in the network, and the M2M devices can use the intra-cluster communication mode to associate with the cluster head or use the cellular communication mode to directly communicate with the cell The base station communicates; the total energy consumption of M2M equipment is modeled as the sum of the energy consumption of all M2M equipment connected to the network, and base...

Abstract

The invention relates to an M2M communication combined clustering and resource allocation method based on energy consumption optimization and belongs to the technical field of wireless communication.The method comprises the following steps: S1, modeling a cluster head selection variable; S2, modeling an inter-machine M2M equipment and cluster head association variable; S3, modeling the total energy consumption of M2M equipment; S4, modeling the total energy consumption of an intra-cluster communication mode; S5, modeling the total energy consumption of a cellular communication mode; S6, modeling limiting conditions for an M2M equipment clustering and resource allocation demand; and S7, based on minimization of the total energy consumption of the M2M equipment, determining a combined clustering and resource allocation strategy. The method provided by the invention can realize the minimization of energy consumption of equipment by optimizing and designing an equipment association and resource allocation strategy while the situation that the M2M equipment is accessed to a network is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, relates to the technical field of M2M resource management, and in particular relates to an M2M communication joint clustering and resource allocation method based on energy consumption optimization. Background technique [0002] Machine-to-Machine (M2M) communication refers to a machine-to-machine communication process without human intervention. The M2M communication method has a wide range of applications and has been widely used in smart grids, smart devices, remote monitoring, smart medical care, smart transportation, smart cities, smart homes and other fields. Usually, the M2M device is small in size, and has certain restrictions on the size and power of the battery. In addition, there are a large number of M2M devices with a wide range, and they are usually deployed in some relatively harsh scenarios where batteries are difficult to replace. Therefore, how to reduce the ene...
