Software Defined Networking (SDN) promises the formidable configuration, vigorous evolution, and satisfactory performance, which are helpful to network operators. Hence, researchers in the field of wireless are increasing their attentions in SDN-related orientation. SDN is still in its initial period. Some essential issues still remain not completely resolved, and the scalability of control plane...
With the wide and prosperous application of wireless communication, it will cause new requirement to the network scalability and flexibility. However, in traditional heterogeneous wireless network architecture, the data plane and the control plane are tightly coupled, and it is very complicated to support flexible control strategy. The novel wireless network architecture based on Software-Defined...
Spectrum sensing, as one of the most important aspects, plays a crucial role on mitigating interference of secondary users (SU) in cognitive radio. However, moving primary user (PU) will sharply decrease the stability of observable information by considerably deteriorating the sensing performance. In this paper, a new joint estimating scheme is proposed for tracking PU proactively and detecting the...
