Abstract
The integration of WLAN and cellular network is the development trend of the next generation mobile communications. With the movement of mobile devices, in order to keep the best quality of service, mobile devices are required to carry seamlessly handoff. The vertical handoff is a key point to solve the seamlessly handoff of heterogeneous networks. A vague based algorithm for vertical handoff in heterogeneous networks is proposed. The algorithm maps parameters to area vague sets, and a new score function on vague set is given, which improves the intelligence of vertical handoff. Our simulation results have proved that the algorithm reduces unnecessary handoff frequencies, and improves the efficiency of vertical handoff.
