Relocation Adaptable Kite: A Scheme to Support Mobility in Named Data Networking

Abstract

Mobile node like smart phone can move at any speed 5 m/s walking speed or in a car at speed 30 m/s. Network and Applications should be intelligent enough to adopt data rate and Interest rate according to any speed and for any duration of active connection between mobile node and access point. The rate at which Interest packets are generated from mobile user in Named Data Networking is called Interest rate. High data rate makes user experience better and low Interest rate means lesser signaling overhead so that underlying network work efficiently specifically in mobile networks. There should be fair trade-off between data rate and Interest rate. In this thesis we propose a novel approach for providing mobility support for mobile producers in Named Data Networking, with significantly lower Interest rate than other available mobility support schemes. Dynamic retransmission timer and advance forwarding plane in Named Data Networking makes the proposed scheme suitable for any speed of mobile node. Dynamic retransmission timer increases the life-time of interest packet on each retransmission of Interest packet. More the count of retransmitted Interest packet lesser the retransmission rate of Interest packet(number of retransmitted Interest per second). And after a sufficient long period of active connection between mobile node and access point, the mobile node become reachable from the routing plane. After that there is no need of creating and maintaining traces. We evaluated our proposed algorithm for 60 different speeds of mobile node ranges from 5 to 300 m/s. A thorough analysis of results shows that proposed scheme performs better with reduced signaling overhead.
