Backbone synthesis in large-scale Mesh WLAN for traffic balance

Mesh WLAN has emerged as a key technology for next-generation wireless networking. With a wide range of Internet-oriented applications with different QoS requirement, the scalability and bandwidth are critical requirement of large-scale mesh WLAN. In this paper, we propose a load-aware adaptive backbone synthesis (LAABS) algorithm automatically balancing the traffic flow in the mesh WLAN. The backbone networks (BNet) will dynamically split into smaller size or merge into bigger one according to statistic load information of backbone nodes (BNs)for traffic balance. Simulation results show LAABS generates moderate BNet size and converges quickly, thus providing scalable and stable BNet to facilitate traffic flow.
