A solution for power consumption costs of WLANS in enterprises

Wireless Local Area Networks (WLANs) have been deployed rapidly in enterprises in order to satisfy user demands for high bandwidth and mobility. For this reason WLANs consist of several Access Points (APs). As a consequence, to this spread of APs, there has been also a substantial increase in energy consumption and economic costs. In order to address this problem, this paper introduces a solution for an energy-aware management of WLANs in enterprises. The proposed solution considers the instantaneous traffic intensity and switches on and off the APs according to the distance value of the client with respect to the AP. The results of real test-bed scenarios reveal that the proposed approach obtains promising performance
