La comunicazione da veicolo a veicolo sta emergendo come una delle nuove tecnologie negli ultimi anni. Può essere utilizzato per varie applicazioni come la sicurezza stradale per evitare incidenti e per fornire servizi di infotainment come multimedia, navigazione, informazioni sul traffico e così via. Dedicated Short-Range Communication (DSRC) insieme alle tecnologie Vehicular Ad Hoc Network (VANET) trovano il loro ambito per lo sviluppo di vari tipi di applicazioni automobilistiche basate sulla comunicazione. I dispositivi DSRC operano alla banda 5,85-5,925 GHz (Sub 6-GHz) e implementano lo standard wireless IEEE 802.11p, specificamente progettato per la comunicazione veicolare. Lo scopo principale della tesi è dimostrare come un messaggio o un'informazione critici vengono inviati su un collegamento wireless da un veicolo sorgente a un veicolo di destinazione selezionando un percorso ottimale. L'obiettivo è anche quello di integrare e calcolare la potenza ricevuta e il rapporto segnale-rumore (SNR) in diverse condizioni come Linea di vista (LOS), Non linea di vista dovuta ai veicoli (NLOSv), Non linea di vista a causa di edifici e fogliame (NLOSb/f). La potenza ricevuta e l'SNR per ciascuna condizione vengono calcolati esplicitamente utilizzando la teoria e gli algoritmi corrispondenti. La ricerca attuale è un'estensione della modellazione del canale veicolo-veicolo basata sulla geometria per la simulazione su larga scala (GEMV2) da cui sono stati estratti i dati e si ottengono le coordinate di latitudine e longitudine. GEMV2 è un pacchetto MATLAB di ray-tracing, che fornisce informazioni dettagliate su come vengono stabiliti i collegamenti wireless tra veicoli in diverse condizioni LOS e NLOS. Considerando le distanze tra veicoli e SNR come variabili decisionali, è stato proposto l'instradamento di pacchetti/informazioni. Infine, l'analisi delle prestazioni è stata effettuata utilizzando le simulazioni 802.11p DSRC Packet Error Rate.

Abstract
Vehicle-to-Vehicle Communication has been emerging as one of the novel technology in the last few years. It can be used for various applications like road safety to avoid accidents, and for providing infotainment services like multimedia, navigation, traffic information and so on. Dedicated Short-Range Communication (DSRC) alongside Vehicular Ad Hoc Network (VANET) technologies find their scope for the development of various types of communication-based automotive applications. The DSRC devices operate at the 5.85-5.925 GHz band (Sub 6-GHz) and implements the IEEE 802.11p wireless standard, specifically designed for vehicular communication. The main aim of the thesis is to demonstrate how a critical message or information is sent on a wireless link from a source vehicle to a destination vehicle by selecting an optimal path.
