  • To solve the problem that current handoff algorithm is not taken into account a variety of properties and prone to ping-pong effect, an algorithm of 3G-WLAN vertical handoff based on the cost function was proposed.This algorithm adopts for the thought of evaluating access network based on cost functions and according to the features of network to analyze the parameters of network and normalized them,so it can handoff decision adaptively and realize the handoff sentence adaptively to the mobile node.The results showed that the algorithm can effectively decrease unnecessary handoff and improve adaptablity of heterogeneous network.
