Abstract:

The coexistence of various wireless access networks has been widely recognized in the next generation network. As a different network access form, how the clients at the instance of their needs will select the access network has become a widespread concern. For this problem, according to the noncooperation between different access networks and the noncooperation relationship between the access network and the clients, a non-cooperative game model based on the payoff function is established. On the basis of the multi-attribute decision theory, the model uses the gray correlation analysis method to normalize the performance parameters of the network, chooses the grey relation grade as the payoff function, compares and selects excellent networks which the clients can access. By solving the Nash equilibrium between the clients and excellent networks, the clients can access the appropriate network. Experimental results demonstrate that the method can effectively select the appropriate network according to the needs of the clients.

Key words: non-cooperative game, Nash equilibrium, gray correlation analysis method, wireless network, selection methods
