Abstract	In communication system each wireless network, mobile terminals (MTs) do not always occupy all spectrum resources, and there exist vacant spectrum holes. Due to the spectrum resource scarcity, cognitive radio can be applied in each wireless network to utilize the vacant spectrum holes. This leads to cognitive heterogeneous wireless networks, where the coverage areas of multiple cognitive wireless networks overlap and secondary MTs can opportunistically utilize the temporary spectrum holes. In cognitive heterogeneous wireless network in order to guarantee QoS for MTs, multihoming 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.
