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 absence of a Peer-To-Peer (P2P) network designed specifically for mobile phones, which has proven extremely popular on fixed networks, is a very attractive topic from an academic research standpoint.
This thesis begins by exploring the work done by the scientific community thus far in the field of mobile Peer-To-Peer.
It then describes a novel approach [1] that utilizes the Session Initiation Protocol (SIP) to carry P2P control messages.
This approach is called P2P-Over-SIP, and has several advantages over other non standard protocols.

We then describe a software implementation using P2P-Over-SIP.
Especially we describe our implementation of a super-peer node, used to build a mobile P2P network with an unstructured semi-centralized architecture.
We detail the results obtained from testing our implementation with realistic usage scenarios.
An analysis of our results is done and conclusions are drawn on the properties of our network.
Lastly we comment on possible future work to be done in this area.
Abstract (fin):Vertaisverkot ovat osoittautuneet hyvin suosituiksi kiinteässä Internetissä.
Akateemisesta näkökulmasta mielenkiintoista on, että matkapuhelinverkkoa varten suunniteltuja vertaisverkkoja ei vielä ole.
Tässä diplomityössä käymme aluksi läpi mobiilivertaisverkosta tehtyjä tutkimuksia.
Tämän jälkeen kuvaamme uudenlaista lähestymistapaa, joka käyttää SIP (Session Initiation Protocol) -protokollaa vertaisverkon merkinantosanomien kuljettamiseen.
Tästä lähestymistavasta, joka tarjoaa useita etuja, käytämme nimeä P2P-over-SIP.

Seuraavaksi kuvaamme mobiilivertaisverkosta tehdyn toteutuksen.
Erityisesti kuvaamme tekemämme supersolmun ohjelmistototeutuksen, jonka avulla puolikeskitetty järjestämätön arkkitehtuuri muodostuu.
Testaamme toteutusta oikeudenmukaisissa skenaarioissa ja tuloksia analysoimalla teemme päätelmiä arkkitehtuurin soveltuvuudesta laajempaan käyttöön.
Lopuksi pohdimme aiheeseen liittyviä kehitysmahdollisuuksia.
