Embodiment Construction

[0143] 1. The present invention constructs a single cell with a radius of 1000m, and simulates two PIoT scenarios, that is, a simple scenario with 10 devices and 5 resource blocks RB, and a scenario with 1000 devices and 300 resource blocks RB. In large-scale connection scenarios, all devices are randomly distributed in the cell (similar to attached figure 1 ),

[0144] Among them, the BS is located at the same location as the edge server, and can provide radio access and computing services for M PIoT devices, and the set of M PIoT devices is expressed as M={1,...,m,...,M} , the PIoT device can put its task on the BS for processing, or it can process it locally,

[0145] The present invention uses a discrete time slot model to divide the total optimization time into T time slots, the duration of each time slot is τ, and the set of T time slots is expressed as T={1,...,t,. .., T}; at the same time, the present invention is a quasi-static scenario, that is, the channel state i...

Abstract

The invention belongs to the technical field of electric power internet of things, and particularly relates to a multi-scale multi-dimensional resource allocation method for massive terminals of the electric power internet of things. The method comprises the following steps: (1) constructing a system model, specifically constructing a PIOT scene based on NOMA-edge computing, wherein the scene is composed of a base station BS, an edge server and a large number of PIOT devices with limited energy and computing resources. (2) refining models, including an equipment end flow model, a local task processing model and a task unloading model; (3) proposing and converting queue time delay constraint and optimization problems, including proposing the queue time delay constraint and optimization problems and converting the optimization problems; (4) performing multi-time-scale and multi-dimensional resource allocation and task division, including resource block allocation, task division and computing resource allocation.

Description

technical field [0001] The invention belongs to the technical field of electric power Internet of things, in particular to a multi-scale and multi-dimensional resource allocation method for massive terminals of electric power Internet of things. Background technique [0002] Power Internet of Things (PIoT) is a typical application of Industrial IoT (IIoT) in the smart grid. In order to realize the interconnection between people, infrastructure and machines, it is necessary Deploy millions of devices. With the rapid development of smart grid services such as demand response, precise load control, and advanced metering infrastructure, each PIoT device will generate a large number of computing-intensive and latency-sensitive tasks. Due to limited energy, storage, and computing resources, it is impractical to handle these demanding tasks on local computing resource-constrained PIoT devices. [0003] Edge computing technology provides an effective solution by deploying edge ser...
