Abstract

Abstract: A main characteristic of the next generation wireless networks is that mobile
terminals can access any networks flexibly. Network selection techniques can improve
spectral efficiency and network capacity. This paper presents an efficient network selection
mechanism based on non-cooperative game. The mechanism can ensure mobile users
to connect to appropriate wireless networks among a heterogeneous network. We show
that the proposed game is a potential game and analyze existence and feasibility of Nash
equilibrium (NE). An iterative algorithm based on best response dynamics for solving the
proposed game is presented. Simulation shows that the algorithm can converge to NE of
the proposed game with a designed utility function, and achieve near optimal performance.

Key words: heterogeneous wireless access networks, network selection, Nash equilibrium
