Vehicle adhoc networks (VANET) are an application of Mobile adhoc networks (MANET). VANET performs management of traffic very well. It also circulates safety information to drivers and passengers in the vehicle. Here, in this paper we have proposed a novel scheme of Sybil attack detection mechanism or algorithm by using which the trajectory path communication among vehicles for identification w...

Wireless access vehicle environment (WAVE) architecture of intelligent transportation system has been standardized in IEEE 802.11p standard and it is going to be widely deployed in many roadway environments in order to provide convenient services. However, the IEEE 802.11p contention-based medium access control protocol would significantly downgrade transmission efficiency between road side uni...

Nowadays, the internet of vehicles (IoV) has been evolved into the stage of vehicle to everything (V2X). However, the majority of existing work focuses on the motor-vehicles. In contrast, the sharing bicycle system is vastly and rapidly deployed as a feasible internet of things (IoT) application scene for the last mile problem (e.g., from station to home/office). Moreover, the internet access o...

A work zone bottleneck in a roadway network can cause traffic delays, emissions and safety issues. Accurate measurement and prediction of work zone travel time can help travelers make better routing decisions and therefore mitigate its impact. Historically, data used for travel time analyses comes from fixed loop detectors, which are expensive to install and maintain. With connected vehicle tec...

This paper addresses an unfairness problem that exists among vehicles of distinct velocities in IEEE 802.11p based vehicle-to-infrastructure (V2I) networks used for drive-thru Internet applications. The standard IEEE 802.11p does not take into account, the residence time of vehicles within the coverage of each road side unit (RSU), for granting channel access. Due to this, a vehicle moving with...

IEEE 802.11p is an approved amendment to the IEEE 802.11 standard to facilitate wireless access in vehicular environments (WAVE). In this article, we present an analytical model to evaluate the impact of vehicle mobility on the saturation throughput of IEEE 802.11p-based vehicle-to-infrastructure (V2I) networks. The throughput model is then used to investigate an unfairness problem that exists ...

Authors have proposed a Novel Combined hybrid Architecture for various vehicular communication scenarios to the advancement of deployed Intelligent Transportation System (ITS). In our Scenario, the existing Dedicated Short Range Communication (DSRC) (IEEE 802.11 p) and Mobile WiMAX (IEEE 802.16 e) acts as an onboard Unit (OBU). As OBUs move between communication range, Vehicle exchange informat...

Vehicular AdhocNETworks (VANETs) relies on continuous data exchange among vehicles and vehicles to roadside units (RSU) to aid road safety, route planning, etc. A transition from free flow to congested traffic on highways often spontaneously originates, despite the fact that the road could satisfy a higher traffic demand. The reasons for such a traffic breakdown are perturbations caused by huma...

Vehicular communications have been subject to a great development in recent years, with multiple applications, such as electronic payments, improving the convenience and comfort of drivers. Its communication network is supported by dedicated short range communications (DSRC), a system composed of onboard units (OBU) and roadside units (RSU). A recently conceived different set-up for the tolling...
