Embodiment Construction

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0021] The invention discloses a task offloading method oriented to location privacy protection, such as figure 1 shown, including the following steps:

[0022] The first step is to generate a virtual position, with the current position l(x,y) as the center and r 1 ,r 2 Form a circle for radius and choose a virtual location l with initial random probability p 1 '(x 1 ',y 2 '), and select another virtual position l on the other side symmetrical to the center of the circle 2 '(x 1 ',y 2 '). The p is a real number from 0 to 1, and ...

Abstract

The invention discloses a task unloading method for location privacy protection. The method comprises the following steps: S1, generating an annular virtual position space by taking a real position of a user as a circle center, and selecting a virtual position according to an initial random probability; S2, acquiring a position of a base station deployed with an edge server nearby by using the virtual position, and constructing a server selection matrix; S3, according to the server selection matrix, preferentially selecting a server to send a task unloading request; S4, allocating bandwidth, and calculating related parameters of task processing; and S5, selecting a task which can be processed within task tolerance time, saves the most energy and time and has the maximum income and unloading the task to an edge node to be executed. According to the method, a task is unloaded by considering the location privacy problem of a user, the location privacy of the user can be effectively protected, the service quality can be obtained as much as possible, a task unloading decision is made by using a reinforcement learning algorithm, and an unloading strategy is dynamically adjusted through online learning.

Description

technical field [0001] The invention belongs to the field of mobile computing, in particular to a location privacy-oriented task offloading method. Background technique [0002] Location privacy protection refers to protecting the user's location information from being disclosed when the location-based service is used, so as to protect other sensitive information of the user from being speculated. More and more researchers have begun to pay attention to the problem of location privacy protection. Edge task offloading means that in edge computing, the edge server selects some tasks from the task offloading request submitted by the mobile device to be processed on the edge node, and the remaining tasks will be processed locally. [0003] The existing location privacy protection methods mainly include anonymity, location obfuscation and encryption. The anonymous method is to conceal the identity of the user, usually by deleting the identity attribute first, and then anonymizi...
