Research on Resource Allocation Based on Immune Algorithm in D2D System.

D2D technology is a communication method in which two users can communicate directly by multiplexing cellular channels. Due to the existence of co-channel interference, research on resource allocation is particularly significant. We first describe the D2D communication scenario and discuss the difference of path loss model between D2D users and cellular users, then summarize the problem as an optimization model to maximize the multiplexed channel throughput. According to this optimization goal, a resource allocation algorithm based on immune theory is proposed, which can find the best multiplexed channels for D2D pairs. The simulation results show that the proposed algorithm can effectively improve the channel throughput compared with the existing literature algorithms.
