Representing & Identifying Things

Maurizio Dècina, Internet del futuro, Roma La Sapienza, 22 maggio 2013

• Any Virtual Object is addressable• Every Virtual Object can be dynamically

associated to a User Identity• Every user can have control over a

specific virtualized object or aggregation of objects

• For each Real Object there is a representation in the cloud for duplications, synchronization, re-creation of the object, etc.

• Actions and events on the Real Object act on network images and clones, and vice versa

Transportation

The transformation of the energy sector (especially electricity) is based on a substantial supply of ICT infrastructure components able to "activate“ the energy transport network

The emerging need for health and social care (also associated with the growth of population life expectancy) finds in ICT a chance to increase effectiveness and efficiency

The spread of cheap and pervasive computing capacity and sensors opens the way for automation applications and mass market Web applications involving personal and public smart objects

ICT offers opportunities to support the growing need of security, safety and efficiency in the transportation sector, in particular for vehicles traffic automation and control

The evolution to on-demand service models, enabled by virtualization and communication networks, offers the opportunity to further advanced scenarios of "utility computing "

Distributed Hash Table - DHTChord: Query Routing


• Properties – Routing table size O(log(N)), where

N is the total number of nodes– Guarantees that a file is found in

O(log(N)) steps• Routing Rule

Upon receiving a query for item id, a node

– Checks whether stores the item locally

– If not, forwards the query to the largest node in its successor table that does not exceed id, or that is equal or immediately greater than id
