Vehicle mobility in presence of obstructing obstacle is one of the main problems limiting the deployment of vehicular ad hoc networks. Indeed, in such a highly dynamic network, underlying routing protocols struggle to find valid routes towards destination nodes. In this paper, we evaluate the performance of Cartography Enhanced OLSR with obstacle awareness protocol (CE-OLSR-OA) as well as Position based OLSR (P-OLSR) and OLSRwith movement prediction (OLSR-MOPR) routing protocols in the context of an urban VANET with obstructing obstacles. In these three OLSR-based routing protocols, the awareness about nodes locations is differently utilized in order to sustain the stability of selected routes. Conducted simulations show the superiority of CE-OLSR compared to OLSR-MOPR and P-OLSR in terms of routes validity, throughput and end-to-end delay metrics. Furthermore, we show that CE-OLSR is more suitable to real time applications than OLSR-MOPR.
