Executive Summary

One of the most widely used wireless communication standards is a Wireless Local Area Network (WLAN) (IEEE 802.11). However, WLAN has a serious power consumption problem. In this paper, the authors propose a novel energy saving approach that exploits the multi-radio feature of recent mobile devices equipped with WLAN and Bluetooth interfaces. Unlike previous approaches, their work is based on clustering. In their work, a cluster is a Bluetooth Personal Area Network (PAN), which consists of one cluster head and several regular nodes. The cluster head acts as a gateway between the PAN and the WLAN, enabling the regular nodes to access the WLAN infrastructure via low-power Bluetooth.
