The wide deployment of Wireless Local Area
Networks (WLAN) we are witnessing today increases
connectivity opportunities for mobile terminal devices, such as
smartphones. However, continuous scanning for WLAN points of
attachment can be a power exhausting mechanism for such
battery-powered devices. These mobile devices, besides being
equipped with different wireless access interfaces, are also
coupled with sensors such as accelerometer, GPS , luminance
and magnetic compass. In fact, sensors are increasingly being
coupled into different devices and environments and are able to
convey sensing information through networks into decision
entities able to optimize different processes. In this paper we
propose a framework where media independent sensing
information is used to enhance wireless link management
towards energy-efficiency. This framework enables the
dissemination of sensing information towards local and remote
decision entities, enhancing other processes (e.g. mobility) with
sensing information in order to provide true Ambient
Intelligence scenarios. We introduce this framework into a
wireless management scenario able to provide energy-efficient
optimal network connectivity.
