Gateway selection based on game theory in internet of things

In the rapid development of wireless communication network technology, the application of Internet of Things (IoT) is increasing day by day. Because the number of end devices is increasing, there is one of important issues about gateway selection for end devices. Therefore, it is important to select the most effective gateway for the application of Internet of Things. Gateway Selection strategy will be a more significant topic at the moment. In recent years, game theory in the network resource allocation or simulation of resource competition has a wide range of applications, not only can clearly understand the game model, but also that the game's equilibrium. In this paper, we focus on non-cooperative dynamic game with end devices for the game players and IoT gateways for the selection strategy. The utility function is derived from the characteristics of players and IoT gateways. Finally, we compare with the maximum received signal strength indicator to meet the overall demands of the end devices and the IoT gateway maximum load difference are superior to the traditional way.
