The need for coupling Heterogeneous Wireless Networks (HWNs) such as WLAN,

WiMAX or UMTS, play a great role in developing towards fourth generation of wireless 

networks. Hence, the algorithms for these networks must be developed especially handoff 

algorithms to present a better performance in such heterogeneous networks. In this paper, 

several projects have different types of networks were implemented and simulated in 

different case studies offered by OPNET simulation to make Intra-technology handoff 

(horizontal handoff) switching in each network and Inter-technology handoff (vertical 

handoff) by interworking between two HWNs. OPNET simulation results show that the 

superiors of WiMAX performance through this research on the WLAN and UMTS networks. 

The performance of WiMAX throughput beats the other networks in much than 30%. Also, 

the simulation results show the successful implementation and simulation of the deployment 

of WLAN into WiMAX and UMTS network by using multiple network interfaces. In this 

work, it found that it is very difficult to successfully complete the vertical handoff between 

WLAN-WiMAX and WLAN-UMTS without carefully and accurately engineering the 

WLAN network due to highlighting the fundamental different in HWNs.
