Architecture for Information Centric Opportunistic Networking (ICON)

Comparison ICON / CCN

Conceptual! Implementation!

Similar to CCN!

•  Node model (PIT, FIB, store)!•  Forwarding engine model!•  Flow control!•  Sequencing!•  Security!

!!

Different from CCN!

•  Decision engine (strategy layer):!•  Different rule management!•  Additional functionality (data

synchronization)!•  Adapted to opportunistic networks!

•  Microsoft.NET / Mono!•  Modular architecture!•  Serialization (protobuffer)!•  Dependency Injection!!

ICON – Demonstration

Described in XML File !10 files to download "

!!!!!!!!!&"

Sends one or more Interest requests !per content!

&!Uses different wireless neighbor for

different type of content!

Checks for Content in local store"&"

Generates Content for!received Interests "

(Read files from disk) "&"

Store Content Segments, for robustness !against file name changes !

&"Returns Content!

Checks for Content in local store"&"

Forwards Received Interests "&"

Store Content upon receive"&"

Returns Content to PIT entries!

Stores Content!
