A traffic class-based network selection scheme for heterogeneous wireless networks

Network selection scheme is important for providing different services, satisfying various QoS requirements, achieving seamless mobility and load balancing in heterogeneous wireless networks, which consist of the integration of various wireless networks especially Wi-Fi (WLAN) and 3G/B3G cellular networks. In this paper, a traffic differentiation-based network selection scheme is proposed in the heterogeneous wireless networks. Simulation results demonstrate that the proposed network selection scheme can decide the optimal network to handoff according to the traffic class.
