Heterogeneous network is a network connecting computers and other devices with different operating systems. Wireless networking is becoming an increasingly important and popular way of providing global information access to users. In a fourth generation communication system, consisting of diverse variety of wireless access standards, network availability, coverage and quality of services may rapidly change depending upon the device mobility and fading suffered by the signal. The main challenges for seamless mobility is the availability of simple and robust vertical handoff algorithms, which allow a mobile node to roam among heterogeneous wireless networks. This paper provides enhanced location awareness of the mobile node and reduction in the adverse effect of fading, so that it is able to predict future network conditions accurately. This paper uses a filtering method named ‘Savitzky-Golay’ smoothening to reduce the effect of fading in the received signal, thereby reducing the unwanted handovers considerably. This paper also considers LTE and Wi-Fi for the ease of study due to their high bandwidth availability and ease of networking
