Radio Resource Allocation in D2D Underlay Communication Using Two Phased Auction Based Fair and Interference Resource Allocation

Abstract

The high demands of the mobile user will affect the workload of eNodeB, which results in the decreasing
performance system of eNodeB. Device-to-Device (D2D) underlaying communication system is a solution in
reducing the workload of eNodeB and increasing the system data rate. This communication system consists
of two users, namely Cellular User Equipment (CUE) and D2D pair, where CUE shares its resources with
the D2D pair. This sharing of resources also causes interference and should be managed using the resource
allocation algorithm. This research used the TAFIRA D2D algorithm and compared it with the greedy
algorithm and the TAFIRA CUE algorithm. The research calculates parameter performance of the system,
such as spectral efficiency, power efficiency, and fairness among D2D pairs. The simulation results show
that Greedy algorithm has a better performance compared with TAFIRA algorithm. TAFIRA D2D only
can achieve 19.94 bps/Hz in spectral efficiency, 23.88 Kbps/watt in power efficiency, and 89% fairness
among D2D pairs.
