Embodiment 1

[0053] See figure 1 , figure 1 It is a schematic flowchart of a load balancing method based on fog computing and cooperative communication network provided by an embodiment of the present invention.

[0054] (a) Obtain an overloaded cell;

[0055] (b) acquiring transfer users in the overloaded cell;

[0056] (c) obtaining the transferred cell of the transferred user;

[0057] (d) Obtain the user who finally performs the task;

[0058] (e) Obtaining the task transfer method of the transfer user;

[0059] (f) Transferring the task of the transfer user to the final task execution user for transmission and execution.

[0060] The embodiment of the present invention proposes a load balancing method based on fog computing and cooperative communication network, and provides a better load balancing method by comprehensively considering time delay and user energy consumption.

Embodiment 2

[0062] Please continue to refer figure 1 , on the basis of the foregoing embodiments, this embodiment focuses on a detailed description of a load balancing method based on fog computing and a collaborative communication network. Specifically, the method includes the following steps:

[0063] Step 1. Calculate the load condition of the cell and obtain the overloaded cell;

[0064] The base station is trusted to obtain the load status of all cells within the coverage area, where the load is the ratio of the physical resource blocks (PRBS) used by the cell to the total physical resource blocks. The load is expressed as:

[0065]

[0066]

[0067] Among them, ρ v represents the reference load of cell v, Indicates the total physical resource blocks of cell v, U v = {1,2,...,u} represents the set of users in cell v, M i Indicates the physical resource block occupied by the task of user i, D i The rate of applying for service for user i, R(SINR i ) can provide the transm...

Embodiment 3

[0164] Please refer to figure 2 , figure 2 A schematic diagram of the working principle of a load balancing method based on fog computing and cooperative communication network provided by the embodiment of the present invention; all communication users work in Orthogonal Frequency Division Multiple Access (OFDMA) mode.

[0165] The micro cell base stations FBS1 and FBS5 are in full load or overload state, and need to be load balanced. The role of the macro cell base station in this patent is to macro-control the micro cell base station and the relay base station. The relay base station Relay5, due to the load of the micro cell base station near the base station They are all in a low-load state and do not need load balancing. Therefore, the macro cell base station MBS will send light sleep control information to the relay base station, making the base station in a light sleep state, reducing the energy consumption of the relay base station, thereby reducing the overall energ...

Abstract

The invention relates to a load balancing method based on fog computing and a cooperative communication network. The method comprises the following steps: (a) obtaining an overloaded cell; (b) obtaining a transfer user in the overloaded cell; (c) obtaining a transferred cell of the transfer user; (d) obtaining a user who ultimately executes a task; (e) obtaining a task transfer mode of the transfer user; and (f) transferring the task of the transfer user to the user who ultimately executes the task for transmission and execution. In the load balancing method provided by the embodiment of the invention, a better load balancing method is provided by comprehensively considering the time delay and the energy consumption of the user, thereby improving the application experience of the user andthe system performance, and reducing the overall energy consumption and the time delay of the system.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a load balancing method based on fog computing and cooperative communication network. Background technique [0002] With the development of mobile communication technology and the explosive growth of data volume, users have higher and higher requirements for data transmission rate. In recent years, cloud computing has developed rapidly, and a large amount of data is calculated and stored in the "cloud". It solves the problem of insufficient storage capacity and low computing power of current smart phones and other devices. [0003] However, the amount of data is growing exponentially. If you still rely entirely on cloud computing, a large amount of data will be processed through a remote server, and then the processing results will be fed back to the device. The transmission time and feedback time will greatly reduce the efficiency of data processing. Fo...
