Energy-aware network selection using traffic estimation

Energy Considerations for a Wireless Multi-homed Environment

“…They perform some tests using a Nokia N95 phone and the Nokia Energy Profiler application (NEP 1 ) to gather the instantaneous power consumption of the phone during the experiment. They found for all strategies that the energy consumed by WLAN is lower than by the 3G interface, which differs with the results presented in [7].…”

“…If for any reason the MS also needs to be located, it has to turn on the GPS and the battery lifetime falls to 9 hours (blue curve). We computed the cost of an individual scanning and found that in average, a single scanning consumes 0.0063% of the battery, differing from the result presented in [7] which claims 0.122% of battery drain per scanning for equivalent battery capacities.…”

“…Some authors have studied the energy impact of data communications using different wireless interfaces. In [7], the author presents an experimental benchmarking of energy consumption of WLAN and 3G interfaces. This experiment consists in downloading and uploading data through a WLAN AP and a 3G network for different load rates and radio link quality.…”

“…These algorithms produce a single-objective optimization to determine the best interface for each application flow. In [7], authors propose a simple energy-aware interface selection technique, which decides to perform a vertical handover (swap all flows from 3G to WLAN) only if the cost of switching to WLAN (i.e., activating the interface and performing scanning) plus the cost of transmitting the data through WLAN is lower than the cost of continuing to transmit the data through 3G. This approach considers a fixed amount of energy per unit of transported data, which is too simplistic to actually represent the interfaces energy consumption, as we will show in Section 2.…”

Energy-budget-compliant adaptive 3D texture streaming in mobile games

“…Also in [36] and [16], the authors argue that frame length details for 802.11 protocols can be used to calculate power consumption for specific data lengths. Their results also show that per-packet energy consumption of network interfaces can be modeled using Equation (1.1).…”
