An Integrated Network with WMAN (WiMax) and WLAN to Provide Better Q.O.S with Vertical Handoff

The integration of WiMAX and WLAN has been seen as a promising approach toward 4G. we are going to analyze different important issues for the interworking of Mobile WiMAX and WLAN networks. We propose a tightly coupled interworking structure. Our proposed schemes can keep stations always being best connected due to ad-hoc nature. An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration, but in this project we are considering the device which has free channel it can share to requester otherwise not.
