“…To achieve technology‐free handover control in IEEE 802.21, the development of the technology‐independent abstraction layer is vital for hiding technology detailed primitives [14]. The standard is expected to allow mobile users (and operators) to take full advantage of overlapping and diverse access networks (ANs) [15]. It provides a framework for efficiently discovering wide range networks and executing intelligent heterogeneous handovers based on their respective capabilities and current link conditions [16].…”
