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

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.
