Abstract

The invention discloses a computing migration method based on task dependency in a mobile cloud environment, and provides an improved algorithm based on a general genetic algorithm idea for solving the problem of multi-task computing migration with dependency in the mobile cloud environment, thereby obtaining a migration scheme with overall excellent response time and terminal energy consumption.On the basis of considering task type subdivision, the computing power of different microclouds is expressed in a refined manner; a calculation task model and a calculation resource model are given; Atime sequence and data double dependency relationship exists between calculation tasks, data transmission between the tasks is reduced as much as possible under the constraint of time sequence and data dependency, the task parallelism is improved, and a utility function calculation method of a migration scheme is given on the basis and is expressed in a mathematical form; And then, a final migration scheme can be obtained by using an improved genetic algorithm, and the scheme has relatively good response time and terminal energy consumption.

Description

technical field [0001] The invention relates to a calculation migration method based on task dependence in a mobile cloud environment, which can be used in the technical field. Background technique [0002] In recent years, mobile smart terminal technology has made great progress, providing mobile applications that meet various needs of users. However, due to its size limitation, mobile terminals always have problems such as weak computing power, small storage space, and insufficient power. The problem of limited resources also restricts the further development of mobile terminals and mobile applications. Therefore, how to expand the resources of mobile terminals has become an urgent problem to be solved. [0003] In order to solve the problem of limited mobile terminal resources, mobile cloud computing technology has emerged. Through computing migration, users can migrate applications to remote clouds or micro-clouds for processing, so as to make up for the resource defect...
