Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] On the basis of analyzing the characteristics of the opportunity network, the present invention introduces the tool of evolutionary game theory, deeply explores the cooperation mechanism and evolution law in the opportunity network, and provides the interaction (cooperation, selfishness, attack, etc.) relationship between the nodes of the opportunity network and evolution dynamics; we believe that nodes in the network have common features with biological evolution, and usually achieve evolutionary equilibrium through continuous evolution (inheritance, mutation), but factors such as society, history, and space will affect the multiple equilibrium of the game. Choices make a difference. The research object of this topic is the opportunistic network group that changes with time and space. The purpose of this invention is to analyze the form...

Abstract

The invention provides an opportunity network evolution algorithm for promoting node cooperation. The algorithm comprises the following steps: firstly, establishing a socialized distributed credit model, including creditability quantification, a direct credit computation method, and an indirect credit evaluation method; secondly, establishing a corresponding incentive model based on creditability, including a creditability-based payoff function design, a creditability optimization based self-adaptive learning mechanism, and the like; thirdly, establishing a multi-population asymmetric evolution model, including multi-population classification, a strategy updating mechanism, and the like; and finally, designing and achieving the evolution algorithm based on the models, including a security cooperation evolution algorithm, and a firefly algorithm for solving the problem of searching the optimum among multiple objects. The evolution model, the credit incentive model and the credit evaluation method provided by the invention are applicable and reliable, and a dynamic security mechanism is operable.

Description

technical field [0001] The invention belongs to the technical field of Internet communication, and in particular relates to an opportunistic network evolution algorithm and a device for promoting node cooperation. Background technique [0002] With the rapid development of smart mobile devices, an impromptu and instant new type of relational network-opportunistic network has emerged as the times require, and it will become a new popular development direction in the next five years after social networks. Social relations in opportunistic networks are based on Topics-interests-needs-locations are randomly generated, such as location-based close encounter communication, or algorithm-based dynamic coupling-relational connections, etc.; it is an innovative application-oriented network form that combines opportunity networks and social networks. [0003] In the communication process of opportunistic networks, messages are transmitted through the cooperative mode of "store-carry-fo...
