Receiver Mobility in Vehicular Named Data Networking

Abstract

This work investigates the topic of Vehicular Named Data Networking (VNDN). We propose a new VNDN routing protocol and address the negative effects caused by receiver mobility. In particular, we identify the problem of Reverse Path Partitioning (RPP) that often prevents Data messages from reaching Content Requesters, degrading application performance. To mitigate RPP we propose a mechanism called Auxiliary Forwarding Set (AFS). AFS takes several mobility factors as inputs and extends the NDN core philosophy by identifying an extra set of eligible nodes to forward Data messages whenever retransmissions are required due to RPP. Simulation results show that AFS is an efficient and scalable solution to improve VNDN application performance regardless of receiver mobility.
