Embodiment 1
[0030] combine Figure 1 to Figure 4, a kind of alliance cooperation green energy allocation method oriented to fog computing provided by the present invention is described in detail, the alliance cooperation green energy allocation method oriented to fog computing of the present invention comprises the steps: S1, based on fog calculation, establish a fog node, multiple The IoT network structure of relay nodes, n renewable energy suppliers, spectrum owners, edge nodes, and terminal devices; in the IoT network structure, renewable energy suppliers are used to provide energy for the IoT network structure, and the edge Nodes are used to centralize terminal devices, and terminal devices are used to transmit data; specifically: data is transmitted from terminal devices to edge nodes, data is concentrated at edge nodes, and edge nodes are transmitted to fog nodes through relay nodes; at the same time, the building is powered by renewable energy. Alliance B={B 1 ,B 2 ,...,B m}, wh...
Embodiment 2
[0037] For the convenience of those of ordinary skill in the art to implement the present invention, an embodiment that includes specific data is provided now, specifically as follows:
[0038] First, a network model is established based on fog computing, which includes a fog node, a relay node, a spectrum owner, an edge node, and a renewable energy supplier that provides energy to the relay node n is taken from 3 to 12 and Terminal equipment access number Q(p)=0.1e -0.1p , p is the fee charged by the fog node to the terminal device, and the terminal device is gathered together through the fog node and connected to the core network through a wireless backhaul link; among them, in the communication link, the frequency of the wireless backhaul link is 25 *10^3GHz, the bandwidth is 20MHz, and the path loss function is L(h)=32.5+20log 10 (f)+10γlog 10 (h)+A×h, in the formula, f is the carrier frequency, γ is the path loss index, gets γ=2.2 in the present embodiment, A=8dm / km, h ...

Abstract
The invention discloses an alliance cooperative green energy allocation method oriented to fog calculation. The method comprises the following steps: S1, establishing an Internet of Things network structure including fog node, relay node, renewable energy provider, spectrum owner, edge node and terminal equipment based on fog calculation; S2, establishing a network structure of the Internet of Things including fog node, relay node, renewable energy provider, spectrum owner, edge node and terminal equipment. 2, establish a leader-follower game model base on a Stackelberg model, wherein a fog node is used as a leader to formulate a wireless network service pricing strategy p for terminal equipment; The renewable energy supplier as a follower determines the price strategy w of the relay nodeaccording to the price strategy p of the wireless network service. A fog node and a preset number of relay nodes are arranged in the network structure of the Internet of Things. Renewable energy suppliers are used to provide energy for the network structure of the Internet of Things, edge nodes are used to centralize terminal devices, and terminal devices are used to transmit data. The invention can improve the stability and data transmission efficiency of the internet of things network structure, and effectively improves the profit of the internet of things network structure.
Description
technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a fog computing-oriented alliance cooperation green energy distribution method. Background technique [0002] Fog computing is a distributed computing, communication, control and storage structure, which is closer to end users than cloud computing, and is a new type of computing platform. Fog computing was proposed by Cisco, which extends the paradigm of cloud computing to the edge of the network, and processes part of the workload and services on local fog devices (such as routers, switches, IP video cameras, etc.) instead of transmitting them to the cloud for processing. [0003] After searching the existing technical literature, it was found that Jianhua He, Jian Wei, Kai Chen and others published a paper entitled "Multi-tier Fog Computing with Large-scale IoT Data Analytics for Smart Cities" paper, this paper proposes a new multi-tier for smart cit...
