Connected Vehicle Technology (CVT) requires wireless data transmission between vehicles (V2V), and vehicle-to-infrastructure (V2I). Evaluating the performance of different network options for V2V and V2I communication that ensure optimal utilization of resources is a prerequisite when designing and developing robust wireless networks for CVT applications. Though dedicated short range communicat...

This paper describes the implementation of a Doppler spectrum measurement platform for narrowband frequency-dispersive vehicle-to-vehicle (V2V) channels. The is based on continuous-wave (CW) channel sounding approach widely used path-loss and large-scale fading measurements, but whose effectiveness to measure V2V channels not equally known. method implemented using general-purpose hardware in c...

In turn, Co-operative Systems are the most promising technology within the ITS framework. The word “co-operative” indicates that vehicles are collaborating with each other and with the infrastructure, exploiting wireless communications, in order to increase their awareness about the road environment. There are two types of communication in co-operative systems, namely vehicle-to-vehicle (V2V) a...

If v are the angles at the vertices v, v 2 V , of a convex n-gon in the plane, then P v2V v = (n?2) { known as Euclid's angle-sum equation. We normalize the full angle to 1, i.e. we set v = v =(2). Then the equation reads as X v2V v = n=2 ? 1 (1) This identity has a generalization to higher dimensions, called Gram's equation. We want to derive this identity by a probabilistic argument. Let us i...

We generalize an existing low-cost analog signal processing concept that takes advantage of the periodicity vehicle-to-vehicle broadcast service to transmitter side. In particular, we propose process multiple antennas using either beamforming network (ABN) phase shifters, or antenna switching (ASN) periodically alternates between available antennas, transmit periodic messages receivers have com...

Along with the rapid development of connected vehicle communication technology, describing following driving status becomes gradually complicated. Driver behavior, type, and road factors affect speed, distance reflects variability. In this paper, a nonlinear model is constructed to characterize The based on full speed difference (FVD), introduces headway time coefficient, type advance response ...

Vehicular adhoc network (VANET) adopts or resembles a similar structure of Mobile adhoc network (MANET). The communication in VANET are generally classified into following three categories such as Vehicle to Infrastructure (V2I), Vehicle to Vehicle (V2V) and Hybrid network which is a combination of V2V and V2I network. VANET using the IEEE 802.11p standard has great potential of achieving objec...

In order to support location-based services, vehicles share their location with a server receive relevant data. Revealing vehicle’s compromises its privacy. One way reduce this problem is obfuscating the by adding artificial noise. However, increases area where true of vehicle may be. Hence, under limited available bandwidth, will provide fewer data location, reducing effectiveness service. To ...

Vehicle-to-vehicle (V2V) communication systems have been studied extensively in recent years by transportation experts worldwide. Such systems enable the transmission of warning messages (alarms) between vehicles without additional roadside infrastructure. Thus, messages can be sent faster than through base stations. Because of these advantages, researchers worldwide are exploring how this tech...
