Tesis doctoral de Daniel Camps Mur
The wi-fi technology has been in the recent years fostering the proliferation of attractive mobile computing devices with broadband capabilities. Current wi-fi radios though severely impact the battery duration of these devices thus limiting their potential applications. in this thesis we present a set of contributions that address the challenge of increasing energy eficiency in wi-fi networks. In particular, we consider the problem of how to optimize the trade-off between performance and energy e¿ciency in a wide variety of use cases and applications. In this context, we introduce novel energy eficient algorithms for real-time and data applications, for distributed and centralized wi-fi qos and power saving protocols and for wi-fi stations and access points. in addition, the di¿erent algorithms presented in this thesis adhere to the following design guidelines: i) they are implemented entirely at layer two, and can hence be easily re-used in any device with a wi-fi interface, ii) they do not require modi¿cations to current 802.11 standards, and can hence be readily deployed in existing wi-fi devices, and iii) whenever possible they favor client side solutions, and hence mobile computing devices implementing them can benefit from an increased energy efficiency regardless of the access point they connect to. Each of our proposed algorithms is thoroughly evaluated by means of both theoretical analysis and packet level simulations. Thus, the contributions presented in this thesis provide a realistic set of tools to improve energy e¿ciency in current wi-fi networks.
