  • Next generation wireless communication network will be an era of over laid heterogeneous networks such as UMTS, WLAN, Wi- MAX and LTE. The user can access these technologies with a mobile node having multiple interfaces. The seamless continuity of service and interoperability in heterogeneous network is achieved by vertical hand off. Vertical hand off across different radio access technologies is facilitated by IEEE802.21 media independent specifications. Among the overlaid heterogeneous radio access technologies, selecting an appropriate candidate network for handover becomes important to remain always best connected. The hand over algorithm must consider QOS parameters to access the performance of different available networks in a physical location. As the mobile nodes move across different networks at high speed, taking quick decision in selecting candidate network become very important. This paper presents a novel method, where candidate network selection is carried at network side with the assistance of mobile node. The proposed method reduces the time required for candidate selection and improves the handover performance.
