Abstract

Wireless Green Networking is a widely used concept in mobile communication systems due to their minimal power consumption, very low costs of installation and considerable ease of deployment. Network deployment, installation and running costs are on the rise owing to the high consumption of power. Current trends, these issues are increasing the effective costs of energy. Energy consumption of a mobile network comes from the BS (Base Station) and is a difficult task to power and heterogeneous network provide low energy consumption with low costs. Here we used wireless LAN in network infrastructures since access points in them are operated continuously to provide connectivity for STAs (stations). In our proposed work we have created wireless radio network which consists of access points. Access points and STAs are placed limited and confined area of about 20 m-square at first. The Mac/physical layer protocol between STAs and APs is IEEE 802.11a and access points are assigned to the different channels so as to prevent interference. In this paper we propose a multi-scenario adaptive station re-association scheme for achieving high power savings for various scenarios including ones in which the number and nature of STAs changes over time. We have proposed a multi-scenario adaptive station redistribution/association scheme for green wireless networking which implements a modified version of the station aggregation and station distribution functions individually in WLANs IEEE 802.11a and evaluated the performance of the scheme under different scenarios through simulation using QualNet simulator.

Keywords: IEEE 802.11a, ROD, Energy Efficiency, Wireless Networking, Station Reassociation, Green Networking.
