  • How to provide fair service for V2I communications in VANETs?

    Publikacja

    In this paper, we focus on fairness issues of Vehicle-to-Infrastructure (V2I) communications. In particular, we show that under a common technique of selection of RSUs by OBUs based on the received signal strength, a vast variability of a number of OBUs connected to RSUs can be observed leading to inefficient/unfair service provided by RSUs. To overcome this problem, we propose an algorithm for RSU selection called RSEL to obtain...

  • Analiza propagacyjna dla komunikacji typu V2X

    W referacie przeanalizowano modele propagacyjne dedykowane dla systemów z komunikacją typu V2I oraz V2V. Następnie przedstawiono wyniki analizy numerycznej tłumienia propagacyjnego. Analizę wykonano dla silnie zurbanizowanego środowiska propagacyjnego z uwzględnieniem warunków LOS i NLOS.

  • A Survey of Vehicular Network Systems for Road Traffic Management

    Publikacja

    In this survey, we analyze the proposals of vehicular communication systems in the context of road traffic management. Starting with the definition of communications between vehicles (V2V), vehicles-to-infrastructure (V2I) and vehicles-to-everything (V2X), we first focus on the requirements and current standards for the Intelligent Transport Systems (ITS), including the maximum communication delay, the communication range and the...

    Communication to and between road vehicles (cars, truck, buses, trains, etc.) are of growing interest. This is partly due to the attractive services that cooperative intelligent transport systems (C-ITSs) provides, mainly in the areas of traffic safety and traffic efficiency. An enabler for C-ITS is wireless vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication, collectively referred to as vehicle-to-X (V2X)...

  • Propagation Loss and Interference Analysis for 5G Systems in the Context of C-ITS System Implementation

    Publikacja

    - Rok 2019

    The article presents the concept of implementing subsequent phases of services for the C-ITS system (the Cooperative Intelligent Transport Systems), based on the European Parliament resolution of March 2018. Next, the 5G systems, in the context of their possible cooperation with C-ITS systems, were discussed. Numerical propagation analysis was performed for V2V and V2I type communication based on two different propagation models....

  • Design of Resilient Vehicle-to-Infrastructure Systems

    Publikacja

    - Rok 2020

    Vehicular ad hoc networks (VANETs) have recently gained noticeable attention due to advantages in improving road traffic safety, shaping the road traffic and providing infotainment opportunities to travellers. However, transmission characteristics following from the IEEE 802.11p standard and the high mobility of VANET nodes remarkably reduce the lifetime, reach and capacity of wireless links, and often lead to simultaneous disruptions...
