Cluster-Based Device Mobility Management (CB-DMM) in Named Data Networking

Abstract

Named Data Network (NDN) was designed to eliminate or end the dependence of IP addresses in hourglass model. Named Data Network was a project started at 2007 by 12 campuses collaboration funded by US National Science Foundation. In Named Data Network routing is based on names instead of IP. When a user needs contents, it will send Interest packet to NDN router. Now it’s up to the NDN router to find the contents and when contents found the router will use the reverse path to send contents through Data packets. NDN support consumer mobility by consumer re-request for data but Producer mobility still under research because locate Producer is tough sometimes. when an active session start between Consumer and Producer and suddenly Producer move from one NDN router to another. Different techniques are used to locate the Producer like Data Replication, Mobile IP, Trace-based and Mapping System, but these solutions have some cons which will be discussed later. We designed a new model to solve this issue and named it Cluster-Based Device Mobility Management in Named Data Network (CB-DMM). In CB-DMM a cluster head has all the information of its attached devices, and when a device move to another router, the router will send attachment information to cluster head and cluster head update the routes. Through CB-DMM model we will also decrease the numbers of interest packets in the network.
