Proposal of Data-Centric Network for Mobile and Dynamic Machine-to-Machine Communication

Abstract

Machine-to-Machine (M2M) communication is expected to grow in networks of the future, where massive numbers of low cost, low function M2M terminals communicate in many-to-many manner in an extremely mobile and dynamic environment. We propose a network architecture called Data-centric Network (DCN) where communication is done using a data identifier (ID) and the dynamic data registered by mobile terminals can be retrieved by specifying the data ID. DCN mitigates the problems of prior arts, which are large size of routing table and transaction load of name resolution service. DCN introduces concept of route attraction and aggregation in which the related routes are attracted to an aggregation point and aggregated to reduce routing table size, and route optimization in which optimized routes are established routes to reduce access transaction load to the aggregation points. These allow the proposed architecture to deal with ever increasing number of data and terminals with frequent mobility and changes in data.

ID-based communication framework for new generation networks

“…Differently from the ID/locator split-based architectures that assign location-independent IDs to hosts, informationcentric networking (ICN) proposals [8][9][10][11] are following a new ID-based communication paradigm where IDs (also called names) are assigned to contents or data objects and are used for the data discovery as well as routing and forwarding. ICN assumes the existing of caching and peer-to-peer functionality as the basic networking service in an application independent manner.…”

“…ICN assumes the existing of caching and peer-to-peer functionality as the basic networking service in an application independent manner. The following four ID-based content communication architectures are reviewed: Content-centric networking (CCN) [8], Network of Information (NetInf) [9], MobilityFirst [10], and Data-Centric Network (DCN) [11].…”

“…DCN [11] focuses on Machine-to-Machine (M2M) communication, where a huge number of low cost, low function M2M terminals communicate in a many-to-many manner in highly mobile and dynamic environments. Its architecture leverages data ID to retrieve dynamic data registered by mobile terminals.…”
