Problems solved by technology

However, simply migrating tasks from a wearable device to a remote cloud server or a nearby mobile device does not always reap the benefits of execution latency or power consumption, such as when a network connection is unstable or unavailable, which can seriously impair user experience.
This is because when the network connection is unstable, the data status and calculation results required by the calculation task may take more time to transmit than the reduction in calculation time brought about by migrating to a node with high computing power.
Smart watches, like smart phones, have high mobility, and the network also has certain instability.

Embodiment Construction

[0033] In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, the following embodiments are given and described in detail with the accompanying drawings as follows.

[0034] The steps of the cloud-end computing offloading method for smart watch applications provided by the present invention are described in detail as follows:

[0035] 1) Marking of offloadable tasks:

[0036] Developers first mark tasks (functions) that are considered offloadable as @offloadable in the smartwatch application. Not all tasks can be offloaded. The offloadable means that the tasks are relatively independent and do not depend on the local characteristics of a specific smart watch, otherwise they cannot be offloaded, such as input and output tasks, which depend on the watch screen and microphone, So it cannot be divided.

[0037] In order to ensure the accuracy of marking, program analysis technology is introduced to build a progr...

Abstract

The present invention provides a cloud-end computing offloading method oriented to smart watch applications. Remove the tasks marked by developers but cannot be offloaded; refactor the offloaded tasks, add remote calling logic and three-layer offloading strategies for smart watches, smartphones and cloud servers under different network conditions; according to offloading The strategy determines whether it is a local call or a remote call, according to which the offloaded tasks are packaged and deployed on the smart watch, smartphone, and cloud server. The present invention also provides a cloud-end computing offloading middleware for smart watch applications.

Description

technical field [0001] The invention belongs to the technical field of software, in particular to a cloud-end computing offloading method for smart watch applications. Background technique [0002] Wearables have experienced explosive growth in recent years and have the potential to become the next popular computing platform. Common wearable devices include smart watches, smart glasses, smart gloves, and VR headsets. IDC predicts that global shipments of wearable devices will exceed 200 million in 2019. Smart watch is one of the most typical and fastest growing wearable devices. At present, the mainstream smart watches include Apple Watch equipped with Watch OS, Gear, LG, Moto360, Huawei, Asus, etc. equipped with Android Wear OS. [0003] The rapid development of smartwatches enables a variety of potential new applications such as mobile augmented reality, voice recognition, and face recognition. These applications greatly facilitate our daily life. However, such applic...
