Heterogeneous networks continue to be operate thanks to the various services they offer, especially in terms of mobility, wide coverage and rapid deployment. However, quality of service (QoS) is a major challenge for these networks, which often consist of different technologies (WiMAX, WIFI, UMTS, LTE, etc.). This study measures and evaluates the behaviour of Web-based applications in a vertical handover context between 802.16e and 802.11e technologies, taking into account all possible QoS mechanisms. The evaluation scenarios were performed using OPNET Modeler. The applications used are: Dynamic web (HTTP + database) and mail flow. The evaluation criteria used are: TCP delay, HTTP load page delay, DB query delay, mail download and upload delay.
