Radio Resource Allocation for Interference Management in Device to Device (D2D) 5G Networks

Due to advancement of wireless communication technology, there is a progressive increase in the number of devices and connectivity each year and this will inevitably overwhelm the base station with the amount of traffic that it has to handle at a time. Device-to-device communication is one of the most significant aspect technologies in the enhancement of moving towards 5G as it is able to solve this problem. Despite that fact, this solution is entailed with an interference problem whereby the resource blocks need to be allocated efficiently in order to minimize its overall interference effect and maximize its throughput. The D2D communication is then further investigated in a more focused and smaller scale network in which we will create a small system model to study the throughput and interference effect of this type of communication. To ensure minimum interference is caused by the RBs allocation problem, a dynamic spectrum algorithm is preferred than the conventional fixed spectrum allocation. The proposed simulation for this project is done by altering one of the parameters that may or may not influence the overall performance of D2D communication. Based on the simulations performed in this project, it is found that the throughput of the system increased by 40.83% and the interference occurred has also slightly improved by an approximate value of 24.15%. Furthermore, the SINR value of the D2D communication has also improved by a significant value of 66.35%, thus, proving that the scheme proposed in this project succesfully improve the overall interference effect in the D2D communication network system.
