HML-Based Smart Positioning of Fusion Center for Cooperative Communication in Cognitive Radio Networks
Amrit Mukherjee, Pratik Goswami, Amlan Datta · IEEE Communications Letters · 2016
This letter addresses the problem of the fusion center (FC) positioning based on the novel approach of hierarchical maximum likelihood clustering for cooperative communication. In a cooperative communication system, the power allocation for all the nodes, including FC, should not be the same all the time, as decision of all the nodes is not required. Using the proposed scheme, the location of the FC based on the cluster formation in hierarchical approach can be made closer to the dense clusters.
