Intelligent Emergency Message Broadcasting in VANET Using PSO
The new type of Mobile Ad hoc Network which is called Vehicular Ad hoc Networks (VANET) created a fertile environment for research. In this research, a protocol Particle Swarm Optimization Contention Based Broadcast (PCBB) is proposed, for fast and effective dissemination of emergency messages within a geographical area to distribute the emergency message and achieve the safety system, this res...
متن کاملNetwork Parameters Evaluation in Vehicular Ad-hoc Network (VANET) Routing Protocols for Efficient Message Delivery in City Environment
Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...
متن کاملMulti-Hop Broadcasting in VANET for Safety Applications: Review and Classification of Protocols
Intelligent Transportation Systems (ITS), which rely on vehicular ad hoc communication networks (VANETs), have the potential to alleviate road accidents and to save lives. Several use cases to VANETs safety applications have been proposed. Most of these applications use multi-hop broadcasting communications to disseminate safety information as far as needed in zones of relevance. A wide variety...
متن کاملPower Control Protocols in VANET
Vehicular Ad hoc Networks (VANET) is one of the most challenging research area in the field of the Mobile Ad hoc Network (MANET), Power control is a critical issue in VANETwhere is should be managed carefully to help the channel to have high performance. In this paper a comparative study in the published protocols in the field of safety message dynamic power control will be presented and evaluated
متن کاملMac Protocols for Vanet
Two major goals of vehicular ad hoc networks (VANETs) are to improve road safety and to increase transportation efficiency. In order to achieve these goals, a reliable and efficient medium access control (MAC) protocol is required. MAC protocols for VANETs must balance the delivery success rate, delay, throughput, bandwidth utilization, fairness and overhead of the transmitted packets. In this ...
