Embodiment Construction

[0035] The invention will be described in further detail below in conjunction with the accompanying drawings of the description.

[0036] Such as figure 1 As shown, the present invention has multiple heterogeneous networks in the wireless ubiquitous communication environment, such as: base station, WLAN, WiMAX and other networks. In this communication model, the source node s is set to be within the scope of the base station to connect to the base station network, and the source node s needs to be connected to the base station network. Send a packet to the destination node d, but the destination node is not within the communication range of the source node s, the source node s can select a relay node to assist the source node in forwarding data in the multi-network overlapping area between the two. Suppose there are M relay nodes around the source node, and the relay node set R={r 1 ,r 2 ,r 3 ,...,r M}, the formed relay node alliance has (2 M -1) Relay alliance set If t...

Abstract

The invention discloses an incentive method for multi-relay node cooperative game. The method is applied to the wireless ubiquitous environment, solves the complex communication problem in the wireless ubiquitous environment, uses game theory to model multi-relay forwarding nodes, and establishes The utility function and cost function of the forwarding node alliance select the optimal relay node forwarding alliance for the source node that needs data transmission service, which greatly promotes the enthusiasm of the relay node for forwarding. At the same time, the method is very simple and easy to implement, has good application prospects, and can well avoid the problem of a single mechanism.

Description

technical field [0001] The invention relates to an incentive method for a multi-relay node cooperative game in a wireless ubiquitous environment, and belongs to the technical field of multimedia 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 widespread and ubiquitous network environment, that is, people are placed in the ubiquitous network, enabling people to 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 tr...
