Abstract.
Wi-Fi hotspots are becoming very popular. Due to limited costs, they are an Effective solution to provide wireless Internet access to nomadic users A key point to exploit The potentialities of Wi-Fi hotspots is managing the scarce energetic resources of mobile Devices. To this end, the IEEE 802.11 standard, a Power-Saving Mode aimed at reducing the energy consumption due to networking activities. In this paper we provide an analytical model of this algorithm. We derive closed formulas for mobile device energy consum ....etc
