Definition

In cognitive heterogeneous wireless networks, the available spectrum resources for each network are dynamic and limited. It is difficult to provision quality of service (QoS) to secondary mobile terminals (MTs). Hence, integrating cognitive heterogeneous wireless networks can help to provide various classes of service to secondary MTs and to support seamless secondary MT roaming. In order to guarantee QoS for MTs, multi-homing technology can be applied, where the data stream from an MT is split into multiple sub-streams, and transmitted over multiple networks by different radio interfaces simultaneously (Xu et al., 2017a,b).

Historical Background

In the fifth generation (5G) mobile communication systems, heterogeneous wireless networks will use various wireless access technologies, e.g., macrocells providing low-to-medium rate services with a large...
