A New Cluster-Based Efficient Broadcast Algorithm for Alert Message Dissemination in VANETs
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 4, Issue 5
Abstract
Data broadcasting is a major operation in VANET networks. So data dissemination management has a great impact on network performance. These networks are studied in two cases: infrastructure-based and infrastructure less networks. Infrastructure-based networks due to the high cost have no more use. The main challenge of networks without infrastructure is dissemination of alert messages. Many methods have been proposed for these networks. The method's simple, p-persistence and EDB have been provided for management of alert messages dissemination. The method's simple and p-persistence have low success rates and faced with the problem of excessive collisions. EDB method has a better performance than the other methods listed. This method is based on the idea that farthest nodes from the origin node disseminate messages. The problem with this approach is that primarily presented for urban roads. Second, once the node may already have received a message again maybe selected as relay nodes that did not need. Third, its delay is too much. So the idea of data broadcast storm management is presented in this paper that works based on the distributed clustering. This new approach performs better in contrast to previously mentioned methods like as EDB in the collision rate, the success rate and delay. Simulation and analyze of tests show the proposed ideas performance.
