Performance Evaluation of the Vertical Handover in the Wireless Networks

Abstract

[EN] In mobile communication, Vertical handover is a process when a mobile switches from one network to another without any interruption. This paper gives three different proposed types of interworking architectures were designed between WLAN, UMTS and WiMAX networks based on the quality of service (QoS). Performance and evaluation of handover based on various parameters like handover delay, received power, signal to noise ratio, throughput, Traffic sent and traffic received is done and the performance of the interworking architecture is analyzed from the simulation results using OPNET Modeller 14.5.
