The heterogeneous network consists of 1 mobile node modeled as multiface node that has three interfaces for the access to WiFI, WiMAX and UMTS technologies. Mobile node is downloading the data from server node. Mobile node is initially getting the data via UMTS. After certain period it detects the signal from WiMAX access point and establishes the connection through it. During mobility, mobile node enters into the region of WiFi access point and handover process occurs.
