This article focuses on improving the vertical handover scheme in the heterogeneous networks. There are three main steps involved in this process which are: Handover necessity estimation, Handover target selection and Handover triggering condition estimation. The first step helps us in finding out whether a handover is necessary to the other access point, the second one helps in finding out the best suited candidates for the handover process. Third step helps us in triggering the handover process at the correct moment. 4G networks are expected to improve the communication process by improving speed and services offered by provider. This method is designed so as to reduce the handover failure and the unnecessary handovers. Along with this it is also supposed to enhance user satisfaction by involving user in decision making. © 2006-2018 Asian Research Publishing Network (ARPN).
