Spectrum Handoff Management in Cognitive HetNet Systems Overlaid With Femtocells
—Cognitive radio networks can facilitate seamless mobility to users considering their effective use of the dynamic spectrum access. This is performed by proactive/reactive adaptation of transmission operations in response to the wireless environment changes. One of these operations includes handoff between various wireless domains. The handoff here is not just a registration with a new base station, but it is also a negotiation to get access to the available channels locally in coexistence with the primary users. This dynamic adaptation between channels known as spectrum handoff (SH) significantly impacts the time of handoff re-connection which raises many questions about the functioning of the cognitive radio solution in the next generation of network systems. Therefore, it is necessary to develop a new method for roaming mobile users especially networks that employ small-cells such as femtocells in order to reduce the unnecessary channel adaptations. This paper proposes a new entit...
