A Network Selection Algorithm Based on Traffic Flow

Abstract:

The existing network selection algorithm generally considering the QoS needs of all services which carried by the terminal. Then selecting an optimal network to access to achieve the overall best of all services, However, for each individual service is not necessarily optimal. To solve the problem above, On the basis of multi-mode terminal and multi- parallel transmission of data, we propose a traffic-based network access selection algorithm, which was designed to realize independent network selection for each traffic flow by considering the network congestion and the transmission of high priority traffic and achieve adaptively network access which making the traffic efficient and reliable transmission, By which each network can be fully utilized. The Simulation results demonstrate that the algorithm can reduce the times of network selection and improve the transmission efficiency and the utilization of network. The results suggest that this kind of network algorithm is effective.
