Abstract EN
A green clustering implementation is proposed to be as the first method in the framework of an energy-efficient strategy for centralized enterprise high-density WLANs.
Traditionally, to maintain the network coverage, all of the APs within the WLAN have to be powered on.
Nevertheless, the new algorithm can power off a large proportion of APs while the coverage is maintained as the always-on counterpart.
The proposed algorithm is composed of two parallel and concurrent procedures, which are the faster procedure based on K -means and the more accurate procedure based on Dynamic Population Size Multiple Objective Particle Swarm Optimization (DPS-MOPSO).
To implement green clustering efficiently and accurately, dynamic population size and mutational operators are introduced as complements for the classical MOPSO.
In addition to the function of AP selection, the new green clustering algorithm has another new function as the reference and guidance for AP deployment.
This paper also presents simulations in scenarios modeled with ray-tracing method and FDTD technique, and the results show that about 67% up to 90% of energy consumption can be saved while the original network coverage is maintained during periods when few users are online or when the traffic load is low.
