Embodiment Construction
[0024] Such as figure 1 As shown, the present invention is a distributed data object storage device based on a wireless communication network, including an APP layer-oriented module, a copy control module, a local search module, a local data object management module, a local storage module, a communication layer-oriented module and a topology management module. in:
[0025] The APP layer-oriented module provides the mobile node with an interface called by the application layer, including storing data, deleting data, browsing data, searching data, and downloading data. This module only encapsulates and converts the parameters and data passed by the above interface, and the specific function execution is completed by the lower copy control module.
[0026] The communication-oriented layer module calls the wireless communication function between nodes, provides transmission of various data and protocol messages, and periodically obtains information such as wireless communicatio...

The invention discloses a distributed data object storage device based on a wireless communication network, and the device is disposed in a mobile node. The device comprises an APP-layer-oriented module, a copy control module, a local search module, a local data object management module, a local storage module, and a communication-layer-oriented module. For a wireless communication environment, a group of moving nodes provide a unified cloud storage and data processing function. For each piece of data placed in a cloud storage, the device can automatically build a plurality of backups and stores the backups in the proper nodes. If a node fails, the device can automatically recover a new example from other backups, and stores the new example in the proper node, thereby guaranteeing the storage robustness of the data object, and achieving the reliable and efficient data sharing and coordination between the moving facilities under the condition of wireless communication.
Description
technical field [0001] The invention belongs to the technical field of communication, in particular to a distributed data storage technology based on the field of wireless communication network communication. Background technique [0002] Cloud storage is a cloud computing system centered on data storage and management. It is a system that integrates a large number of different types of storage devices in the network through application software to work together through cluster applications, grid technology, or distributed file systems, and jointly provide data storage and business access functions. Users can connect to the cloud through any network-connected device to access data conveniently at any time and anywhere. [0003] The cloud storage system is a collection of multi-storage devices, multi-applications, and multi-services. It needs to realize the collaborative work between multiple storage devices. Good data access performance. This requires stable and reliable ...
