Energy Efficient Wifi Tethering on a Smartphone
Energy Efficient Wifi Tethering on a Smartphone Kyoung-Hak Jung†, Yuepeng Qi†, Chansu Yu†‡, and Young-Joo Suh† †Department of Computer Science and Engineering & Division of IT Convergence Engineering Pohang Univ. of Science and Tech., Pohang, 790-784, Republic of Korea Email: {yeopki81, yuepengqi, yjsuh}@postech.ac.kr ‡Department of Electrical and Computer Engineering Cleveland State University, Cleveland, Ohio 44115 Email: [email protected] Abstract—While numerous efforts have been made to save energy of “client” devices but it has not been addressed for access points (APs) as they are assumed to be supported by AC power. This paper proposes E-MAP, which is an energy saving algorithm for a tethering smartphone that plays a role of mobile AP (MAP) temporarily. It saves MAP’s energy by introducing the sleep cycle as in power save mode (PSM) in 802.11 but successfully keeps clients from transmitting while it sleeps. One (a) Nexus One with traffic (b) iPhone 4 with traffic important design goal of E-MAP is backward compatibility, i.e., it requires no modification on the client side and supports PSM and adaptive PSM (A-PSM) as well as normal constant awake mode (CAM) clients. Experiments show that E-MAP reduces the energy consumption of a Wifi tethering smartphone by up to 54% with a little impact on packet delay under various traffic patterns derived from real-life traces.

Dozyap: Power-Efficient Wi-Fi Tethering
DozyAP: Power-Efficient Wi-Fi Tethering Hao Han1,2, Yunxin Liu1, Guobin Shen1, Yongguang Zhang1, Qun Li2 1Microsoft Research Asia, Beijing, China 2College of William and Mary, Williamsburg, VA, USA ABSTRACT Wi-Fi tethering (i.e., sharing the Internet connection of a mobile phone via its Wi-Fi interface) is a useful functionali- ty and is widely supported on commercial smartphones. Yet existing Wi-Fi tethering schemes consume excessive power: they keep the Wi-Fi interface in a high power state regard- less if there is ongoing traffic or not. In this paper we pro- pose DozyAP to improve the power efficiency of Wi-Fi tethering. Based on measurements in typical applications, we identify many opportunities that a tethering phone could sleep to save power. We design a simple yet reliable sleep Figure 1: Wi-Fi tethering. protocol to coordinate the sleep schedule of the tethering phone with its clients without requiring tight time synchro- vices can connect to the mobile SoftAP through their Wi-Fi nization.

Android Y Open Handset Alliance Santiago Diaz Peña
Android y Open Handset Alliance Santiago Diaz Peña Trabajo Práctico TAI2 2010 Ing. Juan de Urraza Ingeniería Informática Universidad Católica “Nuestra Señora de la Asunción” Asunción, Paraguay 1 Introducción En el 2005, Google adquirió Android, una pequeña compañía que recién comenzaba. Los fundadores de Android fueron a trabajar a Google. En ese entonces, era poco lo que se conocía sobre Android, solo que desarrollaban software para teléfonos móviles. Esto genero rumores de que Google estaba planeando entrar en el mercado de la telefonía móvil. En Google, un equipo desarrolló una plataforma para dispositivos móviles basado en el kernel de Linux los cuales fueron promocionados a los fabricantes y prestadores de servicios móviles a partir de la premisa de aportar una sistema flexible y fácilmente actualizable. La Open Handset Alliance fue creada a finales de 2007, liderado por Google con 34 miembros más, incluyendo fabricantes de dispositivos móviles, desarrolladores de aplicación, algunos prestadores de servicios de telefonía móvil y fabricantes de semi-conductores. Android, el software insignia de la alianza, es creado a partir de una licencia de open source y compite contra otras plataformas móviles propietario de Apple, Microsoft, Nokia, Palm, Symbian. El primer teléfono móvil corriendo Android comercialmente disponible es el T-Mobile G1, también conocido como el HTC Dream. Fue aprobado por la FCC en agosto del 2008, estuvo finalmente disponible a finales de octubre. Android nació a partir de la necesidad de crear un plataforma abierta y libre, que pueda ser actualizada, mejorada, modificada para cualquier tipo de teléfono móvil especifico con sus problemas de heterogeneidad por la comunidad de software libre, completa, es decir que tenga todas las funcionalidades que tiene cualquier otra plataforma propietario. -
