Introduction to the topics

Opinnot > T-110.5190 > 2006 > topics.html

During spring 2006 the seminar on Internetworking will focus on mobile communities. In the early years of internetworking in the Internet file transfer, e-mail and WWW were the most popular applications. Later on we have witnessed the power of communities on the Internet, like for example the popular instant messaging and presence systems from late 90's (AOL, Yahoo, MS Messenger, etc). During the same time, other powerful communities were built around e-commerce, like eBay and Amazon, and anti-ecommerce content delivery through p2p networks like Napster, Gnutella, Kazaa, and Akamai. Later on, we have seen the growth of communities around bogs and VoIP (Skype). It seems evident that community networking is a viable, growing trend in the Internet that people are interested about.

The power of community networking will eventually emerge into mobile environments. In (http://www.mobilecommunitydesign.com/) Mobile Community is defined as follows: "A network of interpersonal ties that provides sociability, support, information, a sense of belonging, social identity, and which always connects its members regardless of where they go. It's important to note that location, time and resources are not necessary constraints on membership or participation in a mobile community. However, the community may choose to form based on intended restriction of those variables."

The seminar will focus on mobile communities, though, internetworking between mobile and fixed systems is naturally included in the topic areas. Topics of interest include, but are not limited to, the following.

• Instant messaging (XMPP)
• IRC
• SIP
• QoS
• Chord
• IETF IMPP Framework for Instant Message and Presence Services

• Gatewaying between SIP networks and P2P communication networks
• Evaluation between centralized SIP network and decentralized P2P network
• Mapping of SIP transactions to P2P networks
• Security possibilities and challenges in P2P networks for person to person communications

• Authentication in wireless networks
• Internet Protocol Security Architecture

• Skype Security
• eBay as Identity Provider

• UPnP for the open Internet - a security review
• An overview of service discovery methods for mobile entities
• Analysis of service location protocol interactions

• Investigating Users of Mobile Communites
• Trust Formation in Mobile Communities
• Content Delivery in Multi-Channel Products from User's Point-of-View

• WLAN Roaming Study and its implications to voice services
• Mobile Cellular Services comparison by region
• An evaluation of different broadband wireless technologies and solutions

• Architecture and analysis of MP2P
• Group Management and Communication in MP2P
• Presence Services in MP2P
• Security and Privacy in MP2P
• Interruption handling in MP2P transmission
• Queuing in MP2P system

• P2P SIP
• Social impact on mobile technology
• Mobile game communities

• Mobile Service Extensions to Existing Virtual Communities
• Mobile Gaming for a Mobile Community

• Presence services for communities: The advantages and disadvantages of using presence service
• User Experience: How user ecperience be capttured in systems providing service
• Business models: How the web changes traditional business models

• The formation of ad-hoc data storage spaces in groupwork
  When a group of people meet ad-hoc, how do they set up a space for storing their work? The emphasis is on the ad-hoc aspect, i.e. we do not assume access to a common server etc.
• Data share models in environment with intermittent disconnections
  What data sharing models make sense to the user in an evironment where network connectivity cannot be guaranteed at all times (or is too expensive)?
• Managing changing data in a decentralized/P2P architecture
  How do we manage groupwork, often concurrent, in an environment where it is very hard to provide a globally consistent view of the current state?
• Storage as a utility: scalability, security and archival.
  It has been visioned that we will someday rent or buy the storage capacity we need from an operator in the "Internet cloud", and that local storage devices will merely act as local caches. What would such a system look like?
