Evaluation of performance and scalability of routing protocols for VANETs on the Manhattan Mobility Model

Routing plays an important role in VANETs, even more than conventional mobile ad-hoc networks, because of the high mobility, high density and high velocity of nodes/vehicles on this scenario. Thus, actual research effort is invested on the design of new routing protocols for these networks. The problem is that no considerable previous evaluation of routing was made in VANETS. This must be accurately enough to compare fairly new protocols for VANETs with ad-hoc existing routing ones. This paper presents such evaluation considering an applicable mobility model with velocity and number of nodes analysis.
