ABSTRACT OF DISSERTATION
|
Multi-hop broadcast is one of the main approaches to disseminate data in VANET. Therefore, it is important to design a reliable multi-hop broadcast protocol, which satisfies both reachability and bandwidth consumption requirements. In this work, considering the challenges related to the nature of VANET, we design a number of smart broadcast protocols and evaluate their performance in various network density scenarios. We use fuzzy logic technique to determine the qualification of vehicles to be forwarders, resulting in reachability enhancement. Then we design a bandwidth efficient fuzzy logic-assisted broadcast protocol, which aggressively suppresses the number of retransmissions. We also propose an intelligent hybrid protocol that adapts to local network density. In order to avoid packet collisions and enhance reachability, we design a cross layer statistical broadcast protocol, in which the contention window size is adjusted based on the local density information. We look into the multi-hop broadcast problem with an environment based on game theory. In this scenario, vehicles are players and their strategy is either to volunteer and rebroadcast the received message or defect and wait for others to rebroadcast. We introduce a volunteer dilemma game inspired broadcast scheme to estimate the probability of forwarding for the set of potential forwarding vehicles. In this scheme we also introduce a fuzzy logic-based contention window size adjustment system.
Finally, based on the estimated spatial distribution of vehicles, we design a transmission range adaptive scheme with a fuzzy logic-assisted contention window size system, in which a bloom filter method is used to mitigate overhead. Extensive experimental work is obtained using simulation tools to evaluate the performance of the proposed schemes in terms of reachability, number of rebroadcasts per covered vehicle, and bytes sent per vehicle.
