  Abstract

In the existing ALOHA-Q, which applies reinforcement learning to frame based slotted ALOHA, each node intelligently selects a slot and sends packets without collision. A channel consists of several frames, and a frame consists of several slots. In ALOHA-Q protocol, because each node selects only one slot per frame, network performance is greatly reduced if the frame size and the number of nodes are different. So, in this paper, we apply the objective function to the existing ALOHA-Q to control the number of slots that each node uses within the frame to increase network performance. The simulation results show that the throughput of the proposed algorithm is not sensitive to the number of nodes, and that high performance is produced compared to ALOHA-Q.
