Abstract
With the rapid improvement of wireless networking technologies, current mobile devices can be potentially equipped with multiple interfaces to access different kinds of wireless networks. Thus, there have been many efforts to provide a seamless roaming between heterogeneous networks. However, most previous studies do not address how to select the best possible interface in terms of energy consumption. Therefore, in this paper, we propose to take advantage of accurate location positioning via WWAN interface, so that Mobile Nodes (MNs) obtain the information of hotspot range and completely turn off WLAN interface during idle state, leading to save energy consumption. Simulation results show that our mechanism outperforms existing approaches in terms of energy consumption and signaling overhead.
