On choosing an appropriate path repair design for vehicle-formed mobile ad hoc networks on highways

An information network built on top of vehicles using IVC (inter-vehicle communications) is a type of mobile ad hoc networks (MANET). In the past, many unicast routing protocols for MANET have been proposed. In these protocols, when a routing path breaks, they either locally or globally repair it. Because the topology of an IVC network changes very rapidly on the roads, an established routing path in such a network also breaks very frequently. Finding an appropriate path-repair design for IVC networks is therefore important. This paper compares the performances of a local and a global path-repair design in an IVC network
