The invention discloses a mobile service combined calculation discharge method based on a genetic algorithm. Real time information of mobile terminals, mobile networks and cloud servers are collected; mobile models for calculation discharge are established according to the real time information, the multi-target algorithm based on the genetic algorithm is adopted to perform combined optimization according to the real time information to obtain the calculation discharge strategy based on the genetic algorithm; finally, current mobile service combination is executed according to the mobile models and the calculation discharge strategy based on the genetic algorithm. The problem that a method fails to take mobile characteristics of users into consideration during planning of the calculation discharge scheme and practical performance of the service combination is changed consequently in the prior art, are solved, so that the service combination execution efficiency is increased, and the energy consumption of the mobile terminals is reduced.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for combining calculation offloading of mobile services based on a genetic algorithm. Background technique [0002] In recent years, with the development of mobile terminals dominated by smart phones and tablet computers, mobile terminals have been endowed with more and more functions, but resources such as CPU, memory, bandwidth, and battery capacity on mobile terminals limit the capacity of mobile terminals. ability. With the development of cloud computing technology, virtualization technology and WI-FI technology, it is possible to use WI-FI and 3G / 4G network to offload some tasks on the mobile terminal to the cloud server for execution. Computing offloading in mobile cloud computing is to unload some easily-divided and computationally intensive programs in mobile terminals to nearby available servers for execution through WI-FI or 3G networks, so as to improv...
