In heterogeneous wireless network

most users hope to obtain the most satisfactory network services at a lower cost.This paper proposes a user-centered cost-aware network handoff scheme.Firstly

the model of user's service saturation is established according to the network transmission rate that can be obtained by the user.Secondly

combined with the normalized network cost

network handoff problem can be converted to a multi-objective optimization problem.Considering the network congestion is caused by a large number of users choose the same network at the same time

the user decision behavior in this context is transformed into EI Farol bar problem

and then we get the service saturation expectations of users from the network service probability by searching Nash equilibrium of the problem.Finally

the multi-objective optimization problem is transformed into a maximization problem by considering the reward rate of user's service saturation.Simulation results show that the proposed algorithm can improve the total throughput of the network

reduce the blocking rate of the user's handoff and make the network load more balanced.
