This study proposes an analytical model and an effective scheme for the periodic broadcast on the control channel in vehicular ad hoc networks (VANETs). An improved Markov model for analysing the performance of the periodic broadcast in VANETs is established. Compared with the traditional two-dimensional Markov chain models, the improvement of our proposed model is achieved by the considerations of...
This paper proposes a design and implementation of the On-Board Unit (OBU) in the Vehicular Ad Hoc Network (VANET) for highways, and realizes vehicle-to-vehicle (V2V) communication. The system is divided into four parts including central control module, wireless communication module, GPS module, and human-machine interface module. The hardware platform is consisting of an ARM11-based embedded development...
Vehicular Ad-hoc Network (VANET) is a new application of Mobile Ad-hoc Network (MANET) in the field of Inter-vehicle communication. As the high mobility of vehicles, some traditional MANET routing protocols may not fit the VANET. In this paper, we propose a cluster-based directional routing protocol (CBDRP) for highway scenarios, in which the header of a cluster selects another header according to...
In this paper, an algorithm called DPB (distributed probabilistic broadcasting) is proposed to increase the reliability of the emergent message transmission for safety applications in VANETs (vehicular ad hoc networks). In DPB which is based on probabilistic broadcasting, vehicles compute their own relay probability according to their own states at first, and then retransmit the message on basis of...
