At the present time, various cities are developing wireless network communication to make \"Wireless city\", this can be achieve by integrating Wi-Fi and WiMAX wireless heterogeneous networks and expect to achieve the ubiquitous wireless communication environment. This paper describes the new vertical handoff technique for integration of Wi-Fi (IEEE 802.11) and WiMAX (IEEE 802.1M6) wireless network based on fuzzy comprehensive. The fuzzy comprehensive theory considers various factors like signal to noise ratio, signal strength and terminal moving speed. Simulations of these factors are performed in Network Simulator (NS2, NS3). The result of the experiment will increase the connectivity strength and reduce the ping pong effect.
