Abstract
The effect of the terminal speed and traffic type on the detection and selection process of the preferred access network in the IEEE 802.21 is not yet well understood. Efficiency of vertical handovers depends on the appropriate QoS of the users using mobile devices. One of the most important QoS parameters is the throughput between the base stations and the mobiles. The focus of this paper is to show how IEEE 802.21 standard for media – independent handover services supports mobility and traffic type (voice, video) between UMTS, WiMAX and WLAN networks. In particular, duration of the vertical handover process between UMTS, WiMAX and WLAN is examined (using different mobile terminal speed and traffic type). In order to test the efficiency of vertical handovers, throughput performance during the vertical handovers between heterogeneous networks is also researched in this paper. A novel method for analyzing the vertical handover performance is invented and new conclusions are presented from the simulation results.
