Abstract:
Device to Device (D2D) communication in a cellular network poses some challenges among which are interference and low throughput. These two challenges can be controlled using optimized frequency spectrum reuse (OFSR). OFSR is technique where the user re-uses the frequency of another cell so as to prevent interference of D2D communication devices on the eNB as well as the interference on D2D receiver because of cellular user transmitters. The users were grouped in range of one –one hundred (1- 100), one to two hundred (1 – 200), one to three hundred (1-300) and one to four hundred (1-400). The simulation result obtained shows that OFSR has reduced interference when compared to resource allocation technique. The throughput in the down link is better when compare to the throughput in uplink as seen from the simulation result obtained.
