The vision of the future

The Vision of the Future

  • User expectations:

    • Future applications and platforms will be context-sensitive, adaptive, and personalized

    • They need to be run, in a reasonable and secure manner, on a variety of execution environments: anywhere, anyhow, anytime, by anyone

  • Required system properties:

    • self-aware, distributable, reconfigurable, proactive, collaborative, secure, trusted, privacy providing, mobile, diversely accessible, extendable, incrementally deployable, resource-aware, …


Research challenges in future internet
