Cooperative communication mode based on game theory in wireless ad hoc network

Abstract

The invention pertains to the technical field of wireless self-organized networks, in particular to a cooperative communication method for using game theory in a wireless self-organized network. The method optimizes data transmission quality and node energy consumption by the game behavior of a sending node and a trunk. During optimization process, the sending node provides the relevant information of a data packet to be sent for the trunk which determines whether the data packet is transmitted to the sending node or not according to the credit degree of the sending node and the information of the data packet to be sent. By game process, the sending node is led to obtain more data packets transmitted by the trunk, so as to promote the quality of data transmission and the trunk is also led to consume less energy on transmitting data. The communication way can avoid the defects in a network that 'purely selfish' nodes only take but do not contribute and 'purely selfless' nodes only contribute.

Description

technical field [0001] The invention belongs to the technical field of wireless ad hoc networks, in particular to a cooperative communication method using game theory in the wireless ad hoc network. Background technique [0002] With the development of electronic technology, wireless communication has become more and more popular. Such as mobile phone network, notebook network and so on. With the advancement of technology, traditional wireless network communication methods (such as communication between mobile phones and base stations) can no longer meet people's needs, especially the generation of omnidirectional antennas, making cooperative communication methods gradually enter the big stage of communication. [0003] An omnidirectional antenna means that an antenna can transmit signals to all directions around it at the same time, and can also receive signals from all directions. The difference from traditional directional antennas is that its transmission and reception ...

Problems solved by technology

However, there is a problem in this, that is, when the relay node forwards information, it needs to consume its energy and occupy its bandwidth. Then, even if the route found is optimal, that is, the sum of energy consumption from sending to receiving The smallest, but for relay nodes, it is at a disadvantage, because it needs to consume its own energy to forward data for the sender
