| Popis: | Due to the large-scale deployment of mobile stations, relays, and Access Points (APs), IEEE 802.11ah brings challenges that cannot be effectively addressed in a distributive manner. In this paper, we propose an uplink traffic-aware dynamic association and channel control mechanism for improving multi-hop throughput and delay performances. The proposed software-defined access network estimates throughput for relays and APs considering the stations’ probability of successful transmission. A centralized controller uses the estimated throughput for better decisions in association and channel selection in relays and APs. For improving the capacity of a relay or an AP, a utility function is dynamically measured from the available channels and bandwidth. The proposed association control mechanism allows for seamless handoff throughout the network. Overall, the proposed protocol improves throughput up to 10% and delay up to 13% as compared to the traditional scheme. |
