Today, wireless LAN (IEEE 802.11g/n) has been the dominant wireless network that can provide high data rates in a limited coverage area. While emerging mobile WiMAX (IEEE 802.16e) can provide a wireless broadband access to mobile users in a wide coverage area. These two different technologies will co-exist while complementing each other in some regions, hence, a Mobile Node (MN) with dual interfaces traverses and executes many Hand Overs (HOs) between 802.11g and 802.16e. Meanwhile, there is a huge demand for Voice over IP (VoIP) service over wireless networks.
