CHAPTER III: INFORMATION AND COMMUNICATION TECHNOLOGY<br />
organization. Evolutions <strong>in</strong> the ICT sector are now reflected by the scal<strong>in</strong>g of<br />
network capacities, as well as the abundance of new and <strong>in</strong>novative concepts (e.g.,<br />
<strong>fi</strong>xed and mobile telephony convergence, service-oriented architectures,<br />
ubiquitous <strong>in</strong>formation, ambient <strong>in</strong>telligence, mobile workforce etc.) illustrated <strong>in</strong><br />
the current migration towards Next Generation Network<strong>in</strong>g (NGN) 99 and beyond.<br />
The future becomes even more unpredictable with the onset of various disruptive<br />
technologies, such as, nanotechnology and radio frequency identi<strong>fi</strong>cation (RFID).<br />
A common theme envisioned <strong>in</strong> both the immediate and distant evolution<br />
stages is the migration from networks with centralized management, towards more<br />
flexible networks with widespread autonomous <strong>in</strong>telligence built <strong>in</strong>to their<br />
<strong>in</strong>dividual systems. 100 This flexibility is made possible by the use of IP-based<br />
communications as the common denom<strong>in</strong>ator, allow<strong>in</strong>g seamless service and<br />
application handover (transfer) between heterogeneous <strong>in</strong>frastructures, regardless<br />
of their ownership or underly<strong>in</strong>g technology. To that end, signi<strong>fi</strong>cant changes are<br />
anticipated <strong>in</strong> all conceptual layers:<br />
• Infrastructure Layer: The changes can be viewed from both the network<br />
and user perspectives. On the network-side, there is migration towards<br />
highly connected but survivable mesh architectures, and spontaneously<br />
organized ad-hoc wireless network<strong>in</strong>g for ubiquitous connectivity shorn<br />
of centralized control and <strong>in</strong>frastructure support. On the user-side, there is<br />
the adoption of multi-standard communication devices that can be<br />
automatically recon<strong>fi</strong>gured to function over multiple <strong>in</strong>frastructure<br />
types. 101<br />
• Service Layer: Migration towards context-aware services that adapt<br />
automatically and <strong>in</strong> real-time to the dynamic user context, even<br />
anticipat<strong>in</strong>g user needs, anytime and anywhere. The user context here<br />
refers to the users’ history, personalization and preferences, term<strong>in</strong>al and<br />
network capabilities, location and mobility; organizational restrictions<br />
and procedures; and the operat<strong>in</strong>g environment. The process of adapt<strong>in</strong>g<br />
to a different context should occur without the user necessarily be<strong>in</strong>g<br />
aware of the technical details.<br />
• Application Layer: Migration towards context-aware applications that<br />
adapt automatically and <strong>in</strong> real-time to the dynamic user context and<br />
possibly even anticipate user needs anytime and anywhere.<br />
The <strong>in</strong>centives for aforementioned evolutions from po<strong>in</strong>t of view users (both<br />
<strong>in</strong>dividual users and those with<strong>in</strong> an organization) <strong>in</strong>cludes, the promise of<br />
unfettered access to advanced feature-rich services and applications, <strong>in</strong>creased<br />
ef<strong>fi</strong>ciency and productivity, and flexibility <strong>in</strong> how they utilize them and select<br />
99 In a nutshell, NGN enables the migration from isolated vertically-<strong>in</strong>tegrated application-speci<strong>fi</strong>c<br />
networks (e.g. an organization operat<strong>in</strong>g separate networks for telephony and data services) to<br />
s<strong>in</strong>gle networks capable of bear<strong>in</strong>g all service types (ITU 2007).<br />
100 See, for example, Tafazolli (2005).<br />
101 This refers to devices that are controlled directly by humans (e.g., handsets, PDA, laptop etc.)<br />
as well as those that perform functions remotely on behalf of humans (e.g., sensors embedded <strong>in</strong><br />
cars, furniture, build<strong>in</strong>gs, cloth<strong>in</strong>g etc.). The dual-mode handsets that enable users to connect to<br />
both WiFi and cellular (GSM and 3G) networks are one of the early trendsetters <strong>in</strong> this regard.<br />
