Vehicular ad hoc network (VANET) is a particular class of mobile ad hoc network (MANET) that utilizes moving cars as nodes to establish wireless communications and exchange information between them without the need of infrastructure. VANET is a promising technology used to provide safety, efficiency, and comfort to the road users. Routing protocol has become one of the most challenging tasks for VANET...
Recent years have seen a growing interest in Vehicular Ad hoc Networks (VANETs) and their benefits to the development of intelligent transportation systems (ITS). With the deployment of multimedia services over VANETs, there is a need to develop new approaches to insure higher level of quality of services (QoS) for real time applications, and integrate QoS into routing protocols. However, in VANET...
Quality of Service (QoS) ensures the quality of the network. The proficiency of multiple path formula surmounts the problems of single path routing protocol while transferring the data. But the speedy outgrowth of real time application considers the QoS requirement such as packet delivery ratio, end to end delay, throughput and residual energy. The proposed routing technique ensure that it contributes...
In wireless ad hoc networks such as Vehicular Ad Hoc Networks (VANET), limited coverage of WiFi and high mobility of the nodes generate frequent topology changes. Therefore Quality of Service (QoS) support becomes an essential aspect. In this work we have identified the need for QoS improvement in VANETs. Survey of related work depicts that, an efficient routing strategy plays a crucial role, to improve...
In this paper, we propose a new intersection-based geographical routing protocol, called delay tolerant routing protocol (DTRP) that adapts to the changes in the local topology within city environments. DTRP is based on an effective selection of road intersections through which a packet must pass to reach the gateway to the Internet. The selection, in such delay tolerant VANETs, is made in a way that...
