“…VANET makes extensive utilization of wireless communication to achieve its aims. VANET is a kind of Mobile Ad Hoc Networks (MANET) with some differences, like [1] Limitation in Power: in MANET, power constraint is one of the most important challenges which has shadowed all other aspects namely routing, fusion, on the other hand in VANET, huge battery is carried by the vehicle (i.e. car's battery), so, energy consumption is not a salient issue, [2] Moving pattern: which is random in the MANET while vehicles tend to move in an organized fashion in VANET, and [3] Mobility: there is high mobility in the VANET in comparison to MANET.…”

“…However, selforganization and lack of infrastructure are similarities between MANET and VANET. There are some salient challenges in VANET such as; [1] as mobile nodes (vehicles) moving with high mobility, therefore quick changes in the VANETs topology are difficult to control. [2] The communication between the vehicles is prone to frequent fragmentation.…”

Link duration between two vehicles is considered an important quality of service metric in designing a network protocol for vehicular networks. There exist many works that study the probability density functions of link duration in a vehicular network given various vehicle mobility models, for example, the random waypoint model. None of them, however, provides a practical solution to estimating the link duration between two vehicles on the road. This is in part because link duration between vehicles is affected by many factors including the distance between vehicles, their turning directions at intersections, and the impact of traffic lights. Considering these factors, we propose the extended link duration prediction (ELDP) model which allows a vehicle to accurately estimate how long it will be connected to another vehicle. The ELDP model does not assume that vehicles follow certain mobility models; instead, it assumes that a vehicle's velocity follows the Normal distribution. We validate the ELDP model in both highway and city scenarios in simulations. Our detailed simulations illustrate that relative speed between vehicles plays a vital role in accurately predicting link duration in a vehicular network. On the other hand, we find that the turning directions of a vehicle at intersections have subtle impact on the prediction results.

“…Moreover, a GPS device can be assumed in many cases, whose information improves the network performance in some proposals [Maihöfer, 2004, Mauve et al, 2001, Sun et al, 2006. In the same way, it would be also possible to send packets only to a set of nodes grouped in a geographical area (geocast) [Liao et al, 2000].…”

Evaluation of vehicular ad-hoc networks (VANETs) over real environments is still a remaining issue for most researchers. There are some works which carry out performance tests to evaluate the communication channel according to physical and MAC conditions. Only a few works deal with multi-hop experimentation in this field, and practically none tests multihop protocols. In this paper an integral VANET testbed is evaluated, using 802.11b and a multi-hop network managed by the Optimized Link State Routing protocol (OLSR). Up to four vehicles are used to study the VANET performance over different traffic environments and different metrics are considered to analyse the results in terms of delay, bandwidth, packet loss and distance between nodes. Furthermore, a deeper analysis is carried out to track the routes followed by packets end to end. Since a routing protocol is used, results differ from traditional one-hop and static-route tests, presenting a more realistic study.
