Evaluation of information-centric networking in mobile and distributed environment using wide-area test bed

Information-Centric Networking (ICN) employs communication based on location independent data identifiers (IDs) that enables efficient data dissemination. However, some important challenges still remains in the conventional ICN schemes when they are applied to a highly mobile and distributed environment, such as growth in amount of route information or increased transaction load of name resolution services. To accommodate this, we propose a new ICN scheme where routes are aggregated at aggregation nodes and optimized routes are established during data registration transactions to mitigate the amount of route information, delay, and transaction load. We evaluate the proposed scheme using a nation-wide test bed of 37 intermediate nodes and 336 mobile terminals. We show that the proposed scheme enables efficient data dissemination where the mobile terminals register and retrieve data in widely distributed manner.
