| Summary: | Next generation 4G wireless networks is envisioned as a convergence of different wireless access technologies providing the user with the best anywhere, anytime connection and improving the system resource utilization. However the study of evaluation mobile communication system, mobility management in heterogeneous network, mobility management classification, seamless mobility and handover strategies. In the wireless heterogeneous environment, the majority of problems in the case of handovers stem from the issue of uncertainty in the prediction of network coverage and the duration of availability of network services. The objective of this thesis is to analyze the integration between Universal Mobile Telecommunication System (UMTS) and Wireless Location Area Network (WLAN) during handover process. And then evaluate the impact of seamless vertical handover on the system performance in terms of delay, throughput and packet loss. The simulation tool to achieve the objectives is OPNET 14.5 Modular; we have designed two integration scenarios for Open and Loose coupling scheme and then compared that two integration schemes however result shows that loose coupling architecture is better than open coupling architecture. The results also shows when the user move between two different technology networks shows that loose coupling architecture is better than open coupling architecture in terms of delay, throughput and packet loss. Furthermore the analytical framework extends to multiple radio network environments and the possibilities of the use of Experimental enhance handover operation. |
