Networks
A key component necessary to the development and implementation of pervasive computing are network infrastructures.
The Sapient Corporation[i] is researching the development of intelligent networks. These consist of the following components:
The network
The separation of media and control at the network level will enable dynamic aggregation and delivery of media and services to the most appropriate device via the most appropriate distribution channel.
Network services
Next-generation network protocols and architectures, such as those for distributed systems, will enable the emergence of network services, the definition of users as network services, and the dynamic aggregation of network services.
Network users
The representation of users as permanent network identities and use of intelligent agent technology on the user’s behalf will enable dynamic interaction between multiple users and services within a single context.
Network devices
Fixed and mobile devices, such as PCs, PDAs, TVs, and cell phones, will evolve from functioning individually within a single context to functioning as a collection of related networked devices that share a single context.
Network distribution channels
The maturation of fixed and mobile distribution channels, such as powerline, xDSL, and cellular, and the separation of control and media will enable the emergence of seamless bandwidth.
Conclusion
The vision of pervasive computing in an increasingly networked environment is the most likely future scenario for integrating computing into everyday life. There are issues to be addressed, some of them considerable, but the advantages to disabled users are immediately apparent. Intelligent environments, computer control by everyday activity, and the linking of devices wirelessly all contribute to an ease of use that seems to belong to a distant future. But despite the advanced appearance of the pervasive computing vision, much of the necessary technology is already capable. How regional, national, social and cultural factors will influence the technologies and promise of pervasive computing remains to be seen.
