Abstract: The integration of WIMAX and WiFi has been a promising approach toward 4G. As a result of this integration I, realize totally different vital problems for the interworking of WIMAX and WiFi networks. Thus I planned a tightly coupled interworking structure and additionally planned VHOM schemes which may keep stations continually being best connected because of ad-hoc mode. An ad-hoc network could be a assortment of wireless mobile nodes wherever communication are often done by victimization intermediate mobile nodes. However during this paper I thought of a technology referred to as cognitive Radio technology that provides communication for providing mobile terminals always being best connected to network and also services users special requirements.
