NEMO meets VANET: A Deployability Analysis of Network Mobility in Vehicular Communication

The document analyzes the deployability of approaches for network mobility (NEMO) in wireless vehicular ad hoc networks (VANETs). The vision for VANETs is road safety and commercial comfort applications enabled by short-range wireless technology. For a potential integrated solution of VANETs and NEMO, referred to as ´VANEMO´, we consider a deployable system architecture and define requirements from a holistic view, taking into account economic, functional, and performance aspects. Next, we regard the vehicular network as a conventional mobile ad hoc network (VANET as a MANET), generalize possible solutions and classify them into two comprehensive approaches: MANET-centric and NEMO-centric. We analyze the two approaches with respect to the VANET specific requirements. We conclude that the MANET-centric approach meets the VANET functional and performance requirements better than the NEMO-centric approach.
