Abstract: Disclosed are a method and device for implementing an ad hoc network routing protocol in a multi-agent system. The device includes a trajectory information acquisition module, a data packet delivery module, a delivery confirmation module, a data packet forwarding module, a data transmission feedback module and a data storage module. The method includes: acquiring a separation and rendezvous timing table and an adjacency matrix of an ad hoc network composed of multiple agents at a given moment; if a source node has message sending requirement, performing data packet delivery and delivery confirmation based on the separation and rendezvous timing table and the adjacency matrix; and performing data packet forwarding and transmission status feedback by a non-source node.

Abstract: A data synchronization device is provided, including a control module, a data block storage module and an encoding/decoding module. A data synchronization method using the device is also provided, including: selecting, by the control module, a data transmission network node and selecting the to-be-synchronized data block of a data transmission network node from the data storage module; encapsulating the to-be-synchronized data block in a specific format and then broadcasting the encapsulated data, where if there are two or more to-be-synchronized data blocks, the to-be-synchronized data blocks are encoded and then encapsulated; otherwise, the to-be-synchronized data block is directly encapsulated; processing, by the encoding/decoding module, the encapsulated data to obtain the to-be-synchronized data block, and finally inputting the obtained to-be-synchronized data block into the data block storage module.
