Optimized Energy Conservation in WLAN Using Dynamic Sleep Scheduling

Ajesh. P. A | R. Gowthamani

Abstract: WLAN (Wireless Local Area Network) is used to connect more than one devices using some wireless distribution method and usually providing a connection through an access point to the wider Internet. Wireless LAN becomes popular at home as good as commercial complexes because of its easy installation and it gives the power to move about within a coverage region and still be linked to the network. In WLAN most of the hosts are using battery as their energy resource so energy efficiency is an important consideration for the long lifetime of tthe devices. The mechanisms such as IEEE 802.11 Power Save Mode (PSM), Unscheduled Automatic Power Save Delivery (U-APSD), WMM Power Save (WMM-PS), Dynamic MIMO Power Save and Wake-on-Wireless and Green Call Algorithm are based on the sleep scheduling principle. But the problem is extra delay is added in the absence of proper sleep scheduling, that will affect the delay-constrained applications. The existing system uses an energy-efficient sleep-scheduling protocol and maximizing the sleep period of each node, but the existing mechanism is less energy efficient and reduces the throughput. So, in the proposed system an innovative technique is introduced called Optimized energy conservation for improving energy efficiency.
