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

Abstract (eng): Mobility is one of the key motivations to deploy IEEES02.11 wireless LAN (WLAN).
However, mobility is also a challenge for WLAN.
Some protocols have been standardized or proposed to address mobility in WLAN.
Inter Access Point Protocol (lAPP) is proposed to facilitate the link-layer mobility while Mobile IP (Internet Protocol) is intended to solve the mobility problem in the network-layer if a mobile user has roamed into a different IP subnet.
However, the base Mobile IP protocols do not provide sufficient mobility support to achieve seamless handover, especially for real-time services such as Voice over IP (VoIP).

This thesis presents an in-depth study of the enhancements to the base Mobile IP protocols, and categorizes them.
A new protocol is also proposed in this thesis, which simplifies the handover procedure in base Mobile IP without modifying the MN (mobile node).
