Load Balancing in Wireless Networks using SDN-enabled Infrastructure: Traffic Analysis

The current wireless network has huge problems to deliver the good throughput at minimum packet dropped ratio. The one reason is a lack of resource management which leads to load imbalanced environment. Besides, the typical WLAN architectures are based on proprietary hardware that does not permit to deploy the innovative technologies and network services. Software-Defined Network (SDN) familiarizes as future Internet technology that brings invention in the wireless network paradigm. In order to resolve the load balancing issue, we proposed the SDN-based WLAN environment which contains the load balancer to take a view of each of the resources of WLAN as well as distribute them. It permits the dynamic association and re-association of WLAN clients among the adjacent access points (APs) in each possible situation. The results of simulation demonstrate that the SDN-based WLAN environment ensures that traffic load will not exceed for a long time among adjacent APs, and improve the throughput of associated stations.
