“…In our previous contribution (mroad) [23], the AP selection process uses prior knowledge of the route of the vehicle and the location of the APs along the road. The RSSs of the APs are modeled offline using the CORNER signal propagation model [24]. Based on this information, mroad can predict the best handover location.…”

“…This scenario is exported to the Qualnet [26] network simulator using the Vergilius framework [27]. The RSSs are computed using corner [24], an urban signal propagation model based on knowledge of the road topology. corner computes signal attenuation considering three situations: (i) the AP is in the Line of Sight (LoS) of the MS; (ii) the AP is out of the LoS of the MS with one-corner separation; or (iii) the AP is out of the LoS of the MS with two-corner separation.…”

The increasing number of IEEE 802.11 networks deployed worldwide gives mobile users the possibility of experiencing high-speed wireless access on the move. Moreover, the high density of these deployments in urban areas make IEEE 802.11 a suitable access technology for moving vehicles. However, in order to provide a seamless access to vehicles, the transition between Access Points (APs) must be quick and reliable. The main bottleneck of existing handover mechanisms is the long AP scanning process, which only provides a snapshot of the available networks at a given location, impacting the handover decision on moving vehicles. To overcome this limitation, we propose coper, a context-based predictive handover mechanism that considers vehicle's trajectory, road topology, and network deployment information to decide the best handover location and candidate access points. We validate with real experiments in a city-wide 802.11 network and show that coper can provide better average signal strength, data rate, and connected time than other existing handover approaches.

Abstract-Vehicle to vehicle (V2V) communication has gained renewed interest among research community which is further signified by the allocation of dedicated spectrum and an IEEE standard for their usage in recent years. However, 802.11p, the current IEEE standard for vehicular communications, has a relatively low multiplicity (the number of links that it can simultaneously support). In this work, we propose a new vehicular communication scheme based on sectored antennas in order to improve the multiplicity performance. We first show that a sectored antenna based vehicular communication system has higher multiplicity than 802.11p. To further enable multiple transmit sectors to communicate with a receive node simultaneously in a single receive sector, using an OFDMA system design, we propose a new sector-specific pilot design and corresponding channel estimation over time and frequency domains of the channels corresponding to various sectors. Finally, the performance characteristics of the proposed scheme are shown through simulations.

“…A model for VANETs simulating applied for city area was proposed in [6] with the changing in the speed of nodes after some specific distances was considered. CORNER [7] is a model that predicts path loss for simulation and shows the tradeoff between the accuracy of prediction and computational complexity. Some experimental works for collecting data about path loss and fading to build a statistical model for VANETs simulation was introduced in [8].…”

Abstract-This paper proposes a new approach for modelling Vehicular Ad Hoc Networks (VANETs) based on stochastic geometry and point processes, where road systems are modelled as random lines process and vehicle's locations on a road are linear Poisson point processes. We derive some functions, which show the connectivity properties of VANETs under the impact of fading and path loss, that can be used for large vehicular networks analysis.
