Abstract

The invention belongs to the technical field of network communication, and provides an online self-adaptive computing offloading method and system oriented to marine tasks, obtains environmental information and user information in real time, and establishes an accurate model to describe the current system, thereby realizing efficient task allocation and ensuring timely extension. Therefore, unlike traditional offline methods, we build an offloading model and optimize it in real-time to achieve efficient offloading of device tasks by learning from historical assignment policies to provide current decisions without future information, based on reinforcement learning. The solution of the present invention can not only make full use of energy, but also effectively reduce task delay and ensure QoS.

Description

technical field

[0001] The invention belongs to the technical field of network communication, and in particular relates to an online self-adaptive computing offloading method and system for marine tasks. Background technique

[0002] Ocean buoys play an important role in marine hydrology, water quality and meteorological monitoring, but they will generate computationally intensive and delay-sensitive data processing tasks during operation, which brings great challenges to the computational delay of ocean service tasks. .

[0003] Mobile edge computing can effectively enhance the computing power of mobile devices. The mobile device offloads its own computing tasks to the edge server, and the edge server completes the computing processing of the offloading task and feeds back the calculation results to the mobile device, thereby satisfying the task execution requirements of the mobile device. However, due to the limitations of the special geographical environment at sea, it i...
