With the increasing use of smart phones and other portable communications devices the role of WLAN is increasing. The IEEE 802.11 based WLAN is almost becoming the de facto broadband wireless access network. Due to widespread usage of portable devices the demand for energy efficient networking is increasing. It is necessary to design energy efficient algorithms to prolong the battery life of mobile devices. In this paper, we propose a new link adaptation based energy efficient packet transmission technique for the IEEE802.11g standard. The proposed protocol maintains the QoS of different classes of service at the same time it reduces energy requirements of WLAN based devices thus prolonging the battery life of user devices. The performance of the proposed packet transmission technique is analysed using an OPNET based discrete event simulation model. Simulation results show that the proposed protocol can considerably reduce the energy requirements of mobile devices for data transmission. © 2013 IEEE.
