Ad-Hoc Technology Based Improved Vertical Handover Scheme for Heterogeneous Wireless Networks

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 that means 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. Our main aim is to estimate the conditions of both WiMAX and WLAN networks in terms of available bandwidth and packet delay. For providing the heterogeneous future works with ad-hoc nature
