Abstract: With the fast development of mobile devices and wireless technology, more and more mobile devices are equipped with multiple network interfaces. Particularly, due to its high throughput and low cost, Wi-Fi is becoming one of the most popular interfaces. However, the high power consumption hinders its daily use in mobile devices to some extent. To tackle this problem, we present a Zigbee based Collaborative AP Discovery scheme (ZCAD) in this paper. ZCAD empowers mobile devices to share the ambient AP (Access Point) information (e.g., SSID, signal strength) via Zigbee interfaces, which enables mobile devices to directly associate with the available APs without first scanning them. Extensive experimental results demonstrate that ZCAD can significantly decrease the number of scanning for AP discovery and therefore effectively reduce the power consumption of Wi-Fi communications.

TL;DR: Experimental validation of the CoolSpot system on a mobile research platform shows substantial energy savings: more than a 50% reduction in energy consumption of the wireless subsystem is possible, with an associated increase in the effective battery lifetime.
Minimizing energy for wireless web access with bounded slowdown
TL;DR: The Bounded-Slowdown protocol is presented, a PSM that dynamically adapts to network activity that reduces average Web page retrieval times by 5–64%, while simultaneously reducing energy consumption by 1–14% (and by 13× compared to no power management).

TL;DR: In this paper, the authors propose footprint, leveraging the cellular information such as the overheard cellular tower IDs and signal strength, to guild the Wi-Fi scan and thus reduce the number of unnecessary scans through the changes and history logs of the mobile user's locations.
