TL;DR: This survey provides an overview of energy-efficient wireless communications, reviews seminal and recent contribution to the state-of-the-art, including the papers published in this special issue, and discusses the most relevant research challenges to be addressed in the future.

TL;DR: In this article, a plurality of substantially identical base stations, each capable of being operated as both a primary agent and a secondary agent, are deployed in a wireless communications system, where the secondary agent is capable of communicating with a mobile device and the primary agent is able to communicate with a network.

TL;DR: The analysis of the gains of HTTP content caching at the location of SGW in an LTE Wireless network shows that amongst all the contents, `image' type have the highest revisit rate, which means caching them is beneficial, and provides guidelines for configuring the proxy server for high cacheability benefits.

TL;DR: In this article, a method for locating a mobile device in a wireless communications system comprised of a plurality of base stations is provided, which comprises associating the mobile device with a first base station of the plurality of BSs.

TL;DR: A framework and several analytical results pertaining to the performance of two assignment strategies based on the user's velocity and the amount of data to be transmitted are presented and it is shown that intelligent assignment strategies yield significant gains over strategies that are oblivious to the user profiles.
