Investigation of decision metrics for reuse link selection in device-to-device communication

Device-to-Device (D2D) communication is envisioned to enhance the functionality of future cellular networks. Dynamic frequency reuse in D2D enhanced networks can increase the frequency reuse factor beyond one and has achieved much attention in the last years. To leverage frequency reuse, a proper reuse link selection must be performed. We investigate a core problem of reuse link selection, namely how to find the maximum number of reuse links in a network. Efficient, optimal solutions for this problem have not been found for over a decade in arbitrary wireless network scenarios. We investigate different decision metrics for reuse link selection under dynamic power control and propose a metric that outperforms the known state of the art solutions.
