IP Flow Parallel Access Algorithm Based on Multi-factor in Heterogeneous Wireless Network

Traditional algorithms can only access to a single network, which leads to low utilization ratio of network resource. With the development of mobile communication technology, heterogeneous all-IP network architecture will be used in wireless mobile communication systems. In heterogeneous network, the key is to find a network access algorithm which can achieve high utilization ratio of network resource under the premise of user satisfaction. In this paper, we propose an IP flow Parallel Access Algorithm based on Multi-factor (IPAM). We build the objective cost function by using bandwidth and price as parameters, and then get the optimal flow distributing proportion by making the objective cost function minimum. The algorithm can also be used when multiple networks transmit at the same time. The simulation results show that the algorithm can reduce the price in low network load and balance load in high network load.
