Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): The Wireless Network Interface (WNI) are widely deployed on modern mobile devices, which makes it possible to access internet services such a audio and video streaming from mobile devices.
Due to the intensive computation and network transmission caused by the internet services, power consumption has become big challenge to the mobile devices powered by batteries.
The network transmission cost is mainly caused by the operations of the VNI, such as Receiving/transmitting data or staying in the idle mode.

In this thesis we present an adaptive control algorithm of a wireless network interface (WNI) for energy efficiency.
Our algorithm aims at controlling the operating modes of the WNI in such a way that the WNI can go to sleep mode instead of staying in idle mode when it is predicted to be no traffic for a certain period.
The adaptation takes the overhead of the transition between IDLE and SLEEP modes into account, and the adaptation is combined with an ARIMA-based, prediction algorithm of the traffic patterns.
We evaluate our algorithm with the power measurement from Nokia N810, and the experimental results show that our adaptation can save up to 20% energy than standard PSM during WLAN data transmission in streaming applications such as LiveTV and YouTube.
