Adaptive Energy Centric Radio Access Selection for Vertical Handover in Heterogeneous Networks

Abstract

This paper presents an energy efficient radio access network (RAN) selection for vertical handover between heterogeneous networks. The proposed RAN selection switches evaluation bases by application and adaptively selects a RAN with low energy consumption. In addition, the selection employs a penalty function that avoids discarded vertical handovers to reduce handover overhead and network loading by reducing the integrations.
