2. Sato Lab, GITS, Waseda University Background: Geographic naming strategy A rule to identify a content by using geographic information ICN Based Disaster Information Sharing Service(DISS)

3. Sato Lab, GITS, Waseda University Background: Geographic naming strategy ICN Based Disaster Information Sharing Service(DISS) 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

4. Sato Lab, GITS, Waseda University 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 *Dimitri, Didier, Pieter and Piet, Geometric Information Routing. IEEE ANTS, 2013.

5. Sato Lab, GITS, Waseda University Geographic naming strategy Utilize the locator(geographical names & coordinate names as name prefix) as part of the identifier(content name) to aggregate routing information ICN Based Disaster Information Sharing Service(DISS)

Ogielski, Modeling the Global Internet. Computing in Science and Engg., 1999. Links on campus (non-LAN): 1Gbps, 5ms Links on campus (LAN): 100Mps, 1ms

14. Sato Lab, GITS, Waseda University Simulation ICN Based Disaster Information Sharing Service(DISS) Server-oriented retrieval simulation Disaster Information Size :10MB* * P. Gill et al. YouTube traffic characterization: a view from the edge. In ACM IMC, 2007. Simultaneous Connections:150,300,450,600

15. Sato Lab, GITS, Waseda University Simulation ICN Based Disaster Information Sharing Service(DISS) Retrieval time Location-oriented retrieval simulation Flooding Users send interests with possible names and retrieve matched data back from nodes in specific network. 500 disaster information are distributed in Net 2 and Net 3 with random names and nodes Single user in Net 1 0.961715s 1.61655s

16. Sato Lab, GITS, Waseda University 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
