Problems solved by technology

Resources may be misallocated to devices that transfer very little data, resulting in a huge waste of resources
Furthermore, these works only focus on the short-term optimization of resource allocation while ignoring the long-term network operation goals and constraints
In the long run, this will cause severe performance degradation

Embodiment Construction

[0075] The embodiment of the present invention is divided into two steps, the first step is to build a model, and the second step is to implement the algorithm. Among them, the established system model is as figure 1 As shown, it completely corresponds to the introduction of the massive terminal access model diagram of the power Internet of Things in the summary of the invention.

[0076] 1) For the system model, the base station obtains the type distribution probability of equipment and user needs. Considering that the base station cannot grasp the precise information of the equipment, the common incentive mechanism is no longer applicable, and it is urgent to design an incentive mechanism for information asymmetry. At present, contract theory has been widely used in the optimization of wireless networks. Such as figure 1 As shown, the base station is responsible for resource coordination and task allocation in the cell. After designing the contract, it broadcasts the contr...

Abstract

The invention relates to access control and resource allocation scheme design for mass terminals of the power Internet of Things, and provides a two-stage access control and resource allocation algorithm. In the first stage, the invention provides an incentive mechanism based on a contract theory, and incentive part of delay tolerant machine type communication (MTC) equipment delays the access demand of the MTC equipment so as to obtain a higher access opportunity. In the second stage, based on Lyapunov optimization, the invention provides a long-term cross-layer online resource distribution method, and the method optimizes rate control, power distribution and channel selection in a combined manner under the condition that complete channel state information is unknown. In particular, the joint power allocation and channel selection problem is formulated as a two-dimensional matching problem, and is solved by a pricing-based stable matching method.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to an access control and resource allocation scheme for massive terminals of the electric power Internet of Things. By incentivizing partially delay-tolerant machine-type communication (MTC) devices to postpone their access requirements in exchange for higher access opportunities, the access pressure of base stations during peak hours can be well alleviated. A long-term cross-layer online resource allocation method is designed based on Lyapunov optimization. This method jointly optimizes rate control, power allocation and channel selection when the complete channel state information is unknown, which can improve resource allocation efficiency. Background technique: [0002] The past decade has seen a shift from the mobile internet to the Internet of Things (IoT) era, where billions of physical devices, objects and machines are connected to networks of mobile phones ...
