Vertical handoff is the mutual fused result of heterogeneous wireless network.In the process of vertical handoff, switching decision is a very important link which determines handoff function directly. For the increasing sensor network characteristics,in this paper, it will quote heterogeneous networks which consist of WSN and WLAN as samples to analyze present vertical handoff relative algorithms, by analyzing node moving speed to propose relative vertical handoff algorithms. During the selection procedure of target networks, it analyzed the relative factors in detail which affected network selection. As the residence time of mobile terminals is different in various covered area,it brought in concept of speed thresholds and made improvements for selection algorithm of combined vertical handoff network. The simulation result shows that improved selection algorithm of combined vertical handoff network can choose the best network to access according to mobile terminals moving speed.
