Survey on Handover Techniques for Heterogeneous Mobile Networks

Abstract

This paper presents an overview of existing techniques of Handover in Heterogeneous Mobile Networks. It gives an overview of the mobility management processes and mainly focuses on decision-making approaches. The literature has reported many problems with seamless support for mobility management techniques. Failures in the Handover operation are caused by frequent disconnections and ineffective seamless Handovers. Therefore, to provide customers with an acceptable Quality of Service, Heterogeneous Mobile Networks must have an effective mobility management system that allows many wireless networks to collaborate. A single parameter, two or more extra factors, or a mix of both are used by several mobile controlled Handovers to assess the policy choice. In this paper, We have covered many Handover approaches, as well as advancements that have been achieved throughout time. Almost all of the Handover Techniques over the previous ten years have been covered. Based on the many Advantages and Limitations, we have tabulated all the Handover procedures. The paper will be beneficial to emerging specialists in the sector.
