Abstract EN
Green wireless local area networks (WLANs) have captured the interests of academia and industry recently, because they save energy by scheduling an access point (AP) on/off according to traffic demands.
However, it is very challenging to determine user association in a green WLAN while simultaneously considering several other factors, such as avoiding AP congestion and user migration constraints.
Here, we study the energy-efficient user association with congestion avoidance and migration constraint (EACM).
First, we formulate the EACM problem as an integer linear programming (ILP) model, to minimize APs’ overall energy consumption within a time interval while satisfying the following constraints: traffic demand, AP utilization threshold, and maximum number of demand node (DN) migrations allowed.
Then, we propose an efficient migration-constrained user reassociation algorithm, consisting of two steps.
The first step removes k AP-DN associations to eliminate AP congestion and turn off as many idle APs as possible.
The second step reassociates these k DNs according to an energy efficiency strategy.
Finally, we perform simulation experiments that validate our algorithm’s effectiveness and efficiency.
