• Two major study on ICN’s routing-overlay model: introduce an additional level of indirection between content names and host identifiers-name-based routing model: routing on content names

• Hierarchical renaming would seriously affect compatibility and introduce serious maintenance problems

Background: Geographic naming strategy

ICN Based Disaster Information Sharing Service(DISS)

• name-based routing model: routing on content names

• Since the number of content objects is very large, the routing tables becomes a key concern

• Hierarchical renaming would seriously affect compatibility and introduce serious maintenance problems

• In one word: SCALABILITY

Geographic naming strategy

• Utilize the locator(geographical names & coordinate names as name prefix) as part of the identifier(content name) to aggregate routing information

Naming StrategyCoordinate Resolution

- maximum number of disaster information within a given area.

ICN Based Disaster Information Sharing Service

• Distance between two coordinates is calculated as follows:

• In Tokyo area, one second of coordinate is approximately 30m.• 0.1 second is set as the default minimum unit of coordinates• thus location in unit area of share the same coordinate

Server-oriented Retrieval Strategy

ICN Based Disaster Information Sharing Service(DISS)

Disaster Information is published on server.Users need to send interests to server.

Discussion

ICN Based Disaster Information Sharing Service(DISS)

• Define the Geographic Name for ICN nodes-Distribution of routers depends on geography, traffic burden of the area-Coverage of areas for ICN depends on scale of the nodes, network topology, traffic pattern

• Bi-directional Conversion of GPS Coordinates to Geographic Name

• Content publish and update management-mobile content source

• Duplicate Names
