“…As a default, a two-ray ground-propagation model with an omni-directional antenna height of 1.5 m at receiver and transmitter was selected for which the reflection coefficient was -0.7 [39], which is the same as that of asphalt at this frequency. The plane earth path loss exponent was set to 4.0 (for an urban environment rather than 2.4 for a highway [39]), with the direct path exponent set for free space propagation (2.0). As in IEEE 802.11p, transmission was at 5.9 GHz with a bandwidth of 10 MHz.…”

Abstract-Developing applications, especially real-time ones, for wireless vehicular ad hoc networks (VANETs) requires a reasonable assurance of the likely performance of the network, at the least in terms of packet loss ratios and end-to-end delay. Because wireless propagation strongly influences performance, especially in an urban environment, this paper improves on simpler propagation models for simulations by augmenting ray-tracing derived models of propagation. In the non-line-of-sight component: the propagation distance is more closely calculated according to the reflection distance; the effect of roadside obstacles is included; and for modeling of fast fading a phase factor is introduced, all without necessarily overly increasing computational load. In the line-of-sight component, as well as roadside obstacle modeling: single and double reflections from roadside buildings are added to the standard two-ray ground-propagation model; the distribution of vehicles within a street segment is used to model the ground reflection ray more closely; and the reflection coefficient is also adjusted accordingly to account for reflections from vehicles. The results have been compared with widely-used measurement studies of city streets in the literature, which have confirmed the overall advantage of the improvements, especially in the case of the non-line-of-sight component. A simulation case study shows that in general optimistic performance predictions of packet loss occur with the two-ray ground propagation model when indiscriminately applied.The paper, therefore, represents a way forward for VANET wireless channel modeling in simulations.

Abstract. With the development of Intelligent Transport System (ITS), IEEE802.11p has just been approved as an international standard. However there are still challenging problems to be solved, for example high Doppler frequency shift and high speed hand-off. This paper proposed a method to establish a test platform based on GNU Radio and USRP1.1 to facilitate us further study in this field. The test platform established by us has been verified in two scenarios: low level TCP/IP communication and chat software IPTUX. The results show the test platform established in this paper works well and the average time consumed is 25.15ms for software processing reasons.

“…Since the simulator is only able to specify the range of 100 % successful communications, the assumption of a rather conservative transmission range of 25 m is made. Based on the urban environment of the scenarios, prior research [17] on the communication distance of IEEE 802.11p found the probability …”

Abstract-Vehicular ad hoc networks allow connected vehicles to exchange and share information in order to improve traffic efficiency and safety as well as to provide infotainment functions. In order to cope with the challenging network conditions of the vehicular domain (e.g., intermittent connectivity), a disruptiontolerant networking architecture is suitable. In contrast to pushbased communications (e.g, cooperative awareness messages) used in many proposed vehicular applications, we focus on a query-response model for requesting sensor information. Of particular interest to us is the question how vehicular queries can be efficiently routed to a destination area in such challenged environments, and, more importantly, how the response can be routed back to a moving query originator. We therefore present Breadcrumb Geocast Routing (BGR), a novel disruptiontolerant georouting protocol based on a trail of breadcrumbs left by the query originator. As an overlay protocol, BGR can be used on top of different georouting mechanisms, providing an efficient means to address moving originators. We study the influence of parameters, e.g., breadcrumb size and distance, and prove the effectiveness of the proposed solution in an extensive experimental evaluation, showing that BGR achieves significantly higher delivery rates compared to traditional geocast approaches, while avoiding up to 97 % of the traffic overhead of Epidemic and PRoPHET routing.
