Embodiment Construction

[0011] Before introducing and explaining the present application in detail, in order to better understand the present application, first briefly introduce the general idea of ​​the present application.

[0012] At present, there are many research methods using game theory to enhance the cooperation of selfish nodes in Ad hoc networks, but the current researches are mainly concentrated in the research category of non-cooperative games. In non-cooperative games, the emphasis is mainly on the behavior of the nodes themselves: the strategies that rational nodes can choose in the process of forwarding data packets, the possible results of the game, and the corresponding choices made by nodes. In cooperative games, another research branch of game theory, it is generally assumed that nodes reach an enforceable joint action agreement, that is, nodes may show a "cooperative intention", and this cooperative intention is endogenous. of. At this time, the emphasis is on: what kind of all...

Abstract

The application discloses a method and system for acquiring a distributed overlapping stability coalition structure based on data packet forwarding. The method comprises the steps of: in an integral network for data packet forwarding, determining a coalition structure formed in the network at a current T moment; in the coalition structure, calculating a total revenue of a node i and social welfareof the coalition structure, wherein the node i can be simultaneously added into a plurality of coalitions, and the social welfare is a sum of total revenues of all nodes in the network; and by the total revenue of the node i and the social welfare of the coalition structure, determining the distributed overlapping stability coalition structure when both the total revenue of the node i in the network and the social welfare of the network are the maximum. In the mode, the method and system disclosed by the application can provide technical support for solving the problem of selfish incentive ofnodes in an Ad hoc network.

Description

technical field [0001] The present application relates to the field of wireless network and communication technologies, and in particular to a method and system for obtaining a distributed overlapping stable alliance structure based on data packet forwarding. Background technique [0002] The Ad hoc network is composed of many nodes that can move freely. Each node plays the dual role of host and router. The communication between nodes is completed through wireless channels and multi-hop forwarding of relay nodes. The network does not depend on any fixed infrastructure, has no central control, and is completely self-organizing, so it is very different from traditional wireless networks. In traditional emergency and military applications, the nodes in the Ad hoc network work in a voluntary and active cooperative forwarding mode. However, recently, especially in the civilian field, due to the limitations of various resources such as processing power, storage space, and battery...
