Abstract

Objectives: Advances in the communication system have led to increase in services provided by various Radio Access Technologies. In a heterogeneous environment in order to access these various services, improved handover process is required. In this paper we aim to design a VHO decision algorithm that ensures that a mobile user is transferred to the desired network at an appropriate time in order to maintain better quality of service. Analysis\Methods: Enhanced VHO algortithm can be designed by combining various network selection techniques so that it adapts according to the user and his requirements at that instant of time. This can be done by combining Fuzzy AHP with an optimization technique. Findings: To satisfy increasing user demands in Heterogeneous environment, there is need to design an VHO algorithm that is most effective and efficient with respect to evaluation matrices. Improvement: The network selection technique suggested in this paper proposed the best network selection algorithm along with network selection techniques that will enhance the performance of the network.
