Abstract: Recent advancements in mobile communications, embedded systems, and sen- sors lead to the design of intelligent vehicles. Such vehicles are able to establish wireless communication among themselves, and this is called vehicular ad hoc net- works. A plethora of applications covering safety, e ciency, and infotainment are possible through the use of vehicular networks. Enhancing safety and e ciency is the main goal of an intelligent transportation system (ITS). That is why it is gaining much interest among the research community and automobile industries. Safety-related messages need to propagate e ciently and reliably among mov- ing vehicles to realize safety applications. Variable vehicle density and road topolo- gies in vehicular networks raise many challenges for e cient message dissemina- tion. Furthermore, vehicles must extend message awareness beyond the transmis- sion range of the sending vehicles. The characteristics of vehicular networks, as well as the need to disseminate safety messages over a greater distance, necessitate e cient and reliable multi-hop communications. The current thesis ts into this background and aims to investigate and pro- pose novel and e cient data dissemination protocols, primarily addressing safety applications via vehicle-to-vehicle communication. First, it provides a detailed analysis of message dissemination protocols and their classi cations. The thesis focuses on location-assisted message broadcasting for message dissemination tasks. Native broadcasting methods result in high redundancy and channel contention. Delay-based broadcasting techniques are e cient solutions to reduce excessive re- dundancy and channel congestion. This work provides a comparative analysis of di erent delay-based broadcast techniques. Subsequently, an enhanced adaptive protocol design is presented that is ro- bust against varying vehicle densities and road topologies. The proposed protocol is scalable to accommodate diverse application requirements. Additionally, the behaviour and e ectiveness of the proposed protocol are carefully examined in a realistic environment.
