Abstract

The invention relates to an M2M (Machine-to-Machine) communication network association and power allocation algorithm, and belongs to the technical field of heterogeneous network resource allocation. The method comprises the following steps: step 1), modeling the M2M network energy consumption; step 2), modeling the M2M equipment resource block access probability; step 3), modeling the M2M equipment transmission rate; step 4), modeling the M2M equipment network association and power allocation restricted condition; and step 5), determining an M2M equipment network association and power allocation strategy based on the network energy consumption minimization. The method of the invention can realize the network energy consumption minimization through the optimal design of a network association and transmission power strategy.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to the technical field of heterogeneous network resource allocation, and specifically relates to an M2M communication network association and power allocation algorithm. Background technique [0002] Machine-to-Machine (M2M) communication refers to the process of machine-to-machine communication between devices 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 and other fields. Usually, the M2M device is small in size, and has certain restrictions on the size and power of the battery. Secondly, there are a large number of M2M devices with a wide range, and they are usually deployed in some relatively harsh scenarios. Therefore, batteries are difficult to replace. Therefore, how to reduce the energy consumption of...
