Identity Based Seamless Service Interaction in Heterogeneous Wireless Networks

Background

Users need to be authenticated while accessing the wireless networks and also while retrieving the services from service providers. At some places, it requires minimal authentications and somewhere, it needs to fulfill extremely strict authentication requirements. In the real world, each of us possesses numerous identities for different services we access. When all the information and services are gradually becoming available in the digital world, Identity mechanisms in the digital world should be designed in such a way that it can ensure users’ trust, security and privacy. In such identity system, users should be able to decide how much information they disclose, to whom, and under what circumstances, thereby enabling them to better protect their privacy. This system should also focus on the methods of using different identification mechanisms for the variety of services. Such identity may also enable the personalization of services. We are proposing a digital identity handler that can represent users’ profile, role, presence, location, behavior etc.

Mobile users are expecting continuous service based on seamless access. The user desires to be reachable on all the networks with minimum service interruption. Such environment is very appealing to the user because, independently from the actual carrier network and the terminal, the user experience is very similar. The challenge becomes more serious when users are roaming across heterogeneous wireless networks.

In this research, our goal is to achieve seamless service interaction in heterogeneous wireless network environment based on proposed user identity mechanisms.

Objective

The main objective of the PhD thesis is to make research in the field of identity in the digital world, analyze possible solutions for network and service authentication technologies and investigate the seamless service interaction in heterogeneous wireless networks. The detailed objectives are to

  • study and therefore create & illustrate the overview of role based identity ,
  • make detail analysis of network and service authentication technologies,
  • create functional architecture of seamless service access in heterogeneous wireless networks through role based identity, and
  • design a prototype of seamless service interaction in heterogeneous wireless networks through role based identity.

Planned Outline

The research plan is the following: In the first period from July, 2006 until June 2007, the main task is to do background research on the creation of role based identity and illustrate its overview. Detail analysis of wireless network and service authentication technologies will also be a part the study during this period. The objective is to create a state of the art identity based network and as well as service access architecture.

The outcome of this period is couple of scientific contributions to international projects and international conferences, illustrating an innovative role based identity and possible network and service access through it.

The second year from July, 2007 until June 2008, is allocated to identify the possible candidates for cross network service interaction on seamless fashion. To design a functional architecture of seamless service interaction in heterogeneous wireless networks through role based identity will also be a task in this period.

The outcome of this period is a generic functional architecture of a seamless service interaction in heterogeneous network through proposed identity model. This work will be published through contributions in international projects and conferences.

The third period from July 2008 until January 2008 is allocated for the development of a prototype on the functional architecture created in the second year of research. This prototype shall provide the capability to evaluate the suggested seamless service interaction in heterogeneous wireless network through role based identity model.

The outcome of this period is a state-of-the-art prototype proposed; a comparison study to other such technologies; usage scenarios and a usage analysis. The prototype will be implemented in an operational telecommunication environment, and the overall outcomes will be documented in contributions to conferences and journals.

The last period, from February 2009 until June 2009, is allocated for the documentation of the PhD thesis and its defense.
