Problems solved by technology

The most commonly used incentive method is the auction mechanism, but the auction mechanism can only guarantee the drone to obtain a fixed utility, and cannot maximize the utility of the drone

Embodiment Construction

[0036] In order to facilitate the understanding and implementation of the present invention by those of ordinary skill in the art, the present invention will be further described in detail below with reference to the embodiments. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0037] This embodiment applies the market-driven contract model to the drone traffic offloading task, the base station is the employer issuing the task, and the drone is the employee completing the traffic offloading task and getting a reward. In the UAV incentive mechanism based on contract theory, the base station, as an active contracting party, provides employees with an incentive contract consisting of a series of contract terms, and the contract terms should include the optimal basic salary α * and the optimal bonus coefficient β *. The drone makes its stated effort and informs th...

Abstract

The invention belongs to the technical field of unmanned aerial vehicle traffic unloading, and in particular relates to a design method of a contract mechanism for unmanned aerial vehicle traffic unloading in a heterogeneous cellular network. Apply the market-driven contract model to the UAV traffic offloading task, and establish the base station model and UAV model under asymmetric information; considering the selfishness of UAVs, UAVs may not be willing In the case of participating in multiple traffic offloading tasks, a multi-dimensional contract incentive method is proposed to encourage UAVs to participate in multiple traffic offloading tasks; in view of the fact that the traffic offloading tasks do not affect each other, the problem of task independence is analyzed in the contract design process. Establish a random parameter independent model and a task independent model; by evaluating the performance of drones, the base station will reward and motivate them to participate in traffic offloading tasks and work harder, so as to maximize the utility of drones and base stations.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle traffic offloading, and in particular relates to a design method of a drone traffic offloading contract mechanism in a heterogeneous cellular network. Background technique [0002] Heterogeneous cellular networks are widely regarded as a solution to the explosive growth of data traffic. In a heterogeneous cellular network, when the communication overload of the base station cannot meet the needs of users in the current area, the UAV can be quickly deployed to the target area for traffic offloading. When completing the traffic offloading task in the target area, the UAV consumes various resources, such as data processing and transmission costs, flight consumption, and energy consumption of traffic offloading. Therefore, drones may be less willing to engage in traffic offloading tasks. At the same time, when the UAV participates in the traffic offloading task, in order to pursue mo...
