Coalition game-based self-organizing network node cooperation promotion method and system

Abstract

The invention discloses a self-organizing network node cooperation promotion method and system based on alliance game, including: a starting step: a free node in the self-organizing network sends a node basic information transfer request to its neighbor nodes; the free node receives feedback from its neighbor nodes The basic information of the returned node; the free node obtains the basic information of the alliance to which each neighbor node belongs from the fed back basic information of the node; the free node calculates according to the basic information of the alliance to which each neighbor node belongs If the free node joins the alliance that the corresponding neighbor node belongs to, it will obtain the benefits from the corresponding alliance; select the alliance corresponding to the maximum benefit, and the free node will send a joining request to the alliance corresponding to the maximum benefit, and the alliance will send the joining request according to the free node. In response, the free node that sends the joining request joins the alliance corresponding to the maximum benefit.

Description

technical field [0001] The present disclosure relates to the technical field of Mobile Ad Hoc Networks (MANET), and in particular to a method and system for promoting cooperation of nodes in an ad hoc network based on alliance game. Background technique [0002] The statements in this section merely mention background art related to the present disclosure and do not necessarily constitute prior art. [0003] In the process of realizing the present disclosure, the inventors found that the following technical problems existed in the prior art: [0004] Mobile ad-hoc network is a collection of some wireless mobile nodes, they do not use any existing network infrastructure or central management system, they dynamically form a temporary network, the nodes in the network can move randomly, therefore, the topology of the network may change Make frequent, unpredictable changes. [0005] Secondly, the frequent joining or leaving of nodes in the network brings more dynamic character...

AI Technical Summary

Problems solved by technology

[0011] 1. The topology of mobile ad hoc networks changes frequently, and it is not easy to accurately calculate the virtual currency required for forwarding data packets;

[0012] 2. The evaluation algorithm of selfish nodes needs to be improved: nodes may lose packets due to channel congestion and other problems, and thus be mistakenly identified as selfish nodes;

[0013] 3. When the nodes are affected by the environment such as noise, the accessibility and accuracy of information will also be affected
