Vehicular Ad-hoc Network (VANET) can be envisaged as the network of moving vehicles communicating in asynchronous and autonomous fashion. Efficient and scalable information dissemination is a major challenge due to the movement of vehicles which causes unpredictable changes in network topology. Publish/Subscribe communication paradigm provides decoupling in time, space and synchronization between...
In recent years the research on Vehicular Ad Hoc Network (VANET) has been paid much attention due to the development of wireless network becoming mature, people think highly of traffic safety issue, the popularity of Global Positioning System (GPS), promising applications of VANET being exploited. However, VANET has the essential property of rapid change of large scale network topology. Besides, the...
Routing of data packets in vehicular ad hoc networks (VANETs) is challenging due to dynamic changes in the network topologies. As nodes in VANETs can obtain accurate position information from onboard Global Positioning System receivers, position-based routing is considered to be a very promising routing strategy for VANETs. This paper presents a novel position-based directional vehicular routing (PDVR)...
VANET has become an interesting research field because we can get a lot of benefit from VANET such as to enhance road safety, reduce traffic congestion and etc. However VANET has some drawbacks such as broadcast storm disrupting network communication, rapid topology changes. These problems need solutions to improve VANET's performance. In this paper we propose a new approach to reduce broadcast storm...
