AI Technical Summary

Technical Problem

Existing delay-tolerant network cache management algorithms fail to effectively utilize cache resources, resulting in low business message delivery rates. This is mainly due to ignoring the delivery status and replica distribution of business messages in the network, leading to cache resource mismatch and redundancy.

Method used

A cache management method based on the social nature of connected components is constructed. By extracting the social characteristics of connected components through consensus message broadcasting and multi-hop propagation mechanism, and combining the attributes of business messages themselves, a multi-dimensional cache priority function is designed to achieve accurate screening and retention of high-value business messages.

Benefits of technology

It improves the delivery rate of business messages, reduces cache redundancy, enhances network resource utilization and message delivery efficiency, and is more adaptable than traditional algorithms.

Abstract

The application discloses a delay-tolerant network cache management method, system, device, medium and program product based on connected block sociality, and belongs to the technical field of wireless communication and computer network. The management method comprises the following steps: each node in the delay-tolerant network constructs a connected block society with a limited hop number centering on the node itself, extracts the social characteristics of the node and the business message in the connected block through a consensus message broadcast and multi-hop propagation mechanism, and performs real-time synchronous updating; based on the social characteristics, a multi-dimensional cache priority function is constructed by fusing the properties of the business message, the cache value of each business message is quantified comprehensively, and low-value business messages are discarded when the cache is full; the system, the device and the medium are used for realizing the mechanism; the program product comprises a computer program for realizing the mechanism; and accurate business message screening when the cache is full is realized, so that the arrival rate of the business message is improved.
