Problems solved by technology

Third, there is a contradiction between the limited energy of devices and the requirement of efficient data sharing, because higher data sharing efficiency requires more energy consumption
However, few scholars have conducted research on data sharing under opportunistic, intermittently connected network conditions to maximize network utility.

Abstract

The embodiment of the invention provides an in-cloud collaborative data sharing method and device for mobile equipment, and the method comprises the steps: a data transmission scheduling problem in the cloud of the mobile equipment being formalized into an efficiency maximization problem of data transmission in the cloud of the mobile equipment based on a cloud data sharing model of the mobile equipment; wherein in the efficiency maximization problem, a cooperation excitation mechanism, service quality requirement QoE heterogeneity of different mobile nodes and a multi-interface communicationmode are used as constraint conditions; wherein the cooperation excitation mechanism is used for exciting the mobile nodes to participate in data transmission cooperation, and QoE heterogeneity of different mobile nodes indicates that different mobile nodes have different QoE requirements; wherein the mobile node is the mobile device; and solving the efficiency maximization problem through an online algorithm to obtain an optimal auxiliary variable decision, an optimal data transmission decision and an optimal interface selection decision, so that the data transmission efficiency in the mobileequipment cloud can be maximized.

Description

technical field [0001] The present invention belongs to the technical field of communication, and in particular relates to a method, device, terminal device and computer-readable medium for collaborative data sharing in a mobile device cloud. Background technique [0002] Data acquisition, storage and transmission are important functions of mobile devices, usually each node (including mobile devices and base stations) not only receives data from the remote cloud, but also receives data from various sensors (such as cameras, video recorders and GPS, etc. ) to generate a variety of data (for example, information such as images, videos, voices, and locations). In order to overcome the asymmetry of information between different mobile devices, these data need to be shared among nodes. For example, in disaster areas, users can use mobile devices to share their own situation information to obtain timely rescue and help. Obviously, each mobile node is all from the central node (s...
