Usage of wireless network is growing day by day, so it is very necessary to increase the quality of data delivery. The wireless networks like WLAN, WiMAX and UMTS has its own advantages. By integrating these wireless networks into heterogeneous network architecture, it is possible to improve the Quality of Service. In this paper, WLAN with WiMAX and WLAN with UMTS are integrated and the performances are analyzed by transmitting the voice packets using Voice over Internet Protocol based on parameters such as jitter, delay and Mean Opinion Score value.
