A non-cooperative game incentive method for multi-relay nodes

Abstract

The invention discloses a multi-relay-node non-cooperative game motivating method. The method comprises the steps of setting a double-bounce multi-node united relay transmission communication scene, wherein the scene is provided with a source node s, N relay nodes and a target node d, the source node s needs other nodes to provide transmission service, the N relay nodes are arranged around the source node and can provide transmission service, the node set of the N relay nodes is R=(r1, r2, r3, ... , rN), and the relay nodes are set to be amplified, and transmit signals of the source node to the target node d. Firstly, the assumption scene transmitted by a plurality of relay nodes is set, then a utility function and a cost function of the source node are established through factors such as communication quality index signal to interference ratio and channel capacity, and a virtual currency mechanism, and a total revenue function model of the relay nodes is established through the cost function with fairness and effectiveness; optimal relay node emitting power required by the source node and optimal unit power compensating price of the relay nodes can be obtained through a perfect mathematical derivation solution optimization model, and the existence of Nash equilibrium is proved. The multi-relay-node non-cooperative game motivating method is good in application prospect.

Description

technical field [0001] The invention particularly relates to a non-cooperative game incentive method for multi-relay nodes in a wireless ubiquitous environment, and belongs to the technical field of communication. Background technique [0002] The rapid development of wireless communication technology has promoted the advent of the ubiquitous network era, and the wireless ubiquitous environment refers to the ubiquitous and ubiquitous network environment, that is, people are in the ubiquitous network, so that people can be at any time and place, Use any network to exchange information with any person and thing, based on the needs of individuals and society, use existing network technology and new network technology to provide ubiquitous and all-encompassing information services and applications for individuals and society. It can not only greatly improve the performance of a single network, but also create conditions for the introduction of new services while supporting tradi...

However, in an ad-hoc network, a node is both a terminal and a router. This dual function determines that the node must not only ensure its own normal communication requirements, but also provide other nodes in the network with data forwarding and routing services, that is, between nodes. Need to cooperate with each other to compensate for the lack of infrastructure, otherwise the overall network service cannot be provided

However, considering the factors such as the limited energy, resources and bandwidth of the nodes themselves, especially when the nodes belong to different organizations, the non-cooperative and selfishness between nodes is particularly obvious, which will cause a sharp decline in the overall network performance.
