Interference Reduction Between Device to Device (D2D) Communication

One of the main issues in international mobile telecommunications (IMT) -Advanced systems is how to improve the local area services and spectrum efficiency. Device-to-device (D2D) communication underlay with cellular networks allows direct communication between mobile users. D2D is an attractive approach for dealing with local traffic in 4G cellular networks systems. The purpose of this project is to reduce the interference for D2D communication underlay cellular network and to study the log distance model in different environment with greedy grouping algorithm and compare the results. All results are provided with three different SINR requirements, such as 6dB, 9dB and 12dB for the greedy grouping algorithm. The simulation is applied to lengths 500m, 250m, 100m and 50m for 150 links and 50 links. For each group of links the indoor, free space, urban, sub urban areas are implemented.
