Energy-aware resource allocation in WLAN mobile devices

This paper focuses on low-power usages of mobile devices in WLAN (wireless local area network) environments. Recently, the researchers have been concentrating on power issues for long battery life. However, many of them consider only the MAC (medium access control) protocol. In this paper, we develop a resource allocation algorithm for low-power consumption without considering lower layer protocol. This algorithm provides fairness, efficiency and stability by using an optimization framework in mobile stations. We verify the efficiency of our algorithm by simulation using Intel Centrino/sup /spl trade// parameters, which shows the efficiency of our algorithm.
