D2D particle swarm optimization power control algorithm based on interfence indication
To solve the interference problem caused by D2D communication that is introduced to the cellular network,D2D parti-cle swarm optimization power control algorithm based on interfence indication was proposed.The interference indicator matrix was generated by the interference of cellular users and D2D users which were calculated respectively,to select the best user pai-ring and allocate spectrum resources to D2D users.The transmission power of cellular users and D2D users was adjusted using particle swarm optimization algorithm to improve the overall performance of the system.The simulation results show that the proposed algorithm can effectively improve the system throughput and ensure the fairness of the users compared with other algo-rithms.
