DBA | Simulation parameters | Working mechanism | Observation |
IPACT | ONUs: 8, total bandwidth:1G, OLT-ONU distance: 20 km | The OLT allocate bandwidth for Inter & Intra ONU | Good performance, but it does not support QoS and its centralized |
EDDBA | ONUs: 8, total bandwidth: 1G, OLT-ONU distance: 20 km | Each ONU allocate bandwidth for its own through the OLT broadcasted information | Support QoS, but the decision not optimal efficient. Decentralized, but still need the OLT arbitration |
IDDBA | ONUs: 8, total bandwidth: 1G, OLT-ONU distance: 20 km | The intelligent agent’s communication system provides efficient sharing information protocol between the ONUs | Support QoS, but the decision is rational using agents and the allocation impact is efficiently optimal. Fully decentralized based on decentralized agent’s machinery. Shows good fairness due to collaborative behavior |
