Problems solved by technology

If the grid resource nodes frequently enter and leave different mobile grids, it will cause a large network delay and increase the time required for resources to complete the task. Once the time required by the grid user is exceeded, the task execution will fail.

Embodiment Construction

[0015] The embodiments of the present invention will now be described with reference to the accompanying drawings, in which similar element numbers represent similar elements.

[0016] Before describing in detail the mobile grid resource selection method based on resource mobility in this embodiment, the tasks and resources in the mobile grid environment and the node movement model in the mobile grid resource selection method in this embodiment will be described first.

[0017] Task description in mobile grid environment

[0018] The n mutually independent tasks in the mobile grid are represented as a task sequence T={t 1 , T 2 ,..., t n }. In this embodiment, it is assumed that the task submitted in the mobile grid environment is a meta task, and two conditions are met:

[0019] 1. Each task is atomic and independent, and there is no communication and data dependence between tasks;

[0020] 2. Each resource can only execute one task at a time, and the next task can only be executed af...

Abstract

The invention discloses a mobile network resource selection method based on resource mobility, which comprises the following steps: firstly, determining the mobile grid to which the mobile equipment submitting tasks belongs; if the distances between each mobile resource in the determined grid resource set and a determined mobile grid base station are all larger than the radius of the signal cover of the determined mobile grid base station, re-determining the mobile grid to which a user belongs until the distance between at least one mobile resource in the determined mobile grid resource set and the determined mobile grid base station is smaller than the radius of the signal cover of the determined mobile grid base station; and then finding the mobile resource which is the nearest to the mobile grid base station with determined distance from the determined mobile grid resource set, allowing the nearest mobile resource to implement tasks. The method can effectively ensure the stability of data transmission between a user and the resource and reduce network time delay brought by mobility, is favorable to shorten the time for completing tasks and can improve the success rate of task implementation.

Description

Technical field [0001] The present invention relates to a grid task scheduling method, in particular to a mobile grid resource selection method based on resource mobility. Background technique [0002] In recent years, with the advancement of wireless technology and mobile technology, various mobile devices have appeared, such as smart phones, personal digital assistants (PDAs, Personal Digital Assistants) and laptops, etc. The number of these mobile devices It is quite huge and can provide a certain amount of computing power to meet the needs of the grid system. Therefore, mobile devices are being incorporated into the grid system and become a part of the grid system. Adding the mobile device to a conventional grid composed of fixed personal computers or servers constitutes a mobile grid (Mobile Grid). [0003] In the mobile grid, mobile devices can play two roles: one is as an interface for accessing grid resources; the other is as a grid resource. The former only uses mobile d...
