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.

Symbian application design
Abstract (eng):The Internet family of protocols (TCP/IP) has dominated the computer network communications; offering services such as worldwide web (WWW), file transfer (FTP), e-mail and voice-over-IP (VoIP) to the scientific, research and business communalities and to the common users.
The TCP/IP protocols are also merging with other telecommunication paradigms such as 3G and 4G cellular networks.
Despite of wide deployment, TCP/IP protocols are ill suited for some extreme networks because of some strict fundamental assumptions regarding end-to-end communication, built-into their architecture.
These assumptions do not always hold in the emerging challenged networks such as mobile ad hoc networks, deep space communication, sensor networks, low earth orbiting (LEO) satellites etc., because of variable requirements of bandwidth, longer end-to-end delays, intermittent connectivity and higher error rates.

Delay-Tolerant Networking tries to solve some of the issues by relaxing many of the assumptions used in the TCP/IP regarding end-to-end communication.
It defines an overlay network for end-to-end message delivery, which uses the Bundle protocol.
In the thesis work, we have implemented the Bundle protocol stack for Symbian based smart phones to extend DTN for mobile phone based interpersonal communication and the networks formed by socializing of people.
We have also designed and implemented a convergence layer for Bluetooth.
The software architecture is generic, extensible and provides API for the development of customized DTN applications for mobile phones.
