TL;DR: This work presents experimentally obtained results that evaluate the energy efficiency of the base standard in comparison with the latest 802.11n version, and is the first to provide such a detailed comparative analysis on the performance of both standards.

TL;DR: This work proposes an efficient scheme for cell planning by employing spectrum sensing techniques, and appropriately select the center frequency inside the operating band, towards maximizing the quality of the end user experience.

TL;DR: The NITOS Bikes Net platform is presented, a city-scale mobile sensing infrastructure that relies on bicycles of volunteer users that employs a custom-built embedded node that can be equipped with different types of sensors and which can be easily mounted on a bicycle in order to opportunistically collect environmental and WiFi measurements in different parts of the city.

TL;DR: This work focuses on online assessment of spectrum occupancy with respect to sensing delay and energy efficiency, and proposes a real-time spectrum sensing engine that implements parallel processing on software defined radios in terms of the aforementioned metrics.

TL;DR: A tiny device able to fit in the battery pack of smartphones and monitor the resulting power consumption in an on-line way and demonstrate how the diversity of experimental conditions and configurations can significantly impact energy consumption is developed.
