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

    2. The Internet of the Future The Semantic Web (knowledge) The Ubiquitous Web (people & objects) Social Networks Semantic Web Internet of Things Web Services Increasing Knowledge Networking The Web (information) The Social Web (people) Increasing Social Networking After Nova Spivak, Radar Networks & Mills Davis, Project 10x Maurizio Dècina, Internet del futuro, Roma La Sapienza, 22 maggio 2013

Representing & Identifying Things An Individual, Uniquely Addressable Resource Web- Oriented Architecture (WOA) Resource Examples: Web page Customer Orders Products Blog posts Stock quotes Geolocations Map tiles Headshots Call records Podcasts Ajax components Web widgets Advertisements OpenOffice docs URI typeformat Web markupHTML, XHTML Data XML, ATOM, JSON Images JPG, SVG, PNG Video MPEG, AVI, H.264 Code Jsvascript, SWF Interact via HTTP • Non exhaustive list of • possiblerepresentations • Links (URIs) to globallyunique • resources, in lieu of copies WOA/Client Source: Dion Hinchcliffe, 2008 • 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 • 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 Maurizio Dècina, Internet del futuro, Roma La Sapienza, 22 maggio 2013

    10. Managed Internet Services (QoS) Cloud Computing • The evolution to on-demand service models, enabled by virtualization and communication networks, offers the opportunity to further advanced scenarios of "utility computing " Internet of Things • 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 Smart Grid • 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 e-Health • 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 Intelligent Vehicle Transportation • 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 Maurizio Dècina, Internet del futuro, Roma La Sapienza, 22 maggio 2013

    21. 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 Succ. Table i id+2i succ 0 1 1 1 2 2 2 4 6 Items 7; 0 0 Succ. Table 1 i id+2i succ 0 2 2 1 3 6 2 5 6 7 query(7) Item 1 6 2 Hash size=3 bit 4 nodes, 8 items Succ. Table i id+2i succ 0 7 0 1 0 0 2 2 2 Succ.
