A Survey of Vehicular Ad hoc Networks Routing Protocols

摘要: In recent years, the aspect of vehicular ad hoc network (VANET) is becoming an interesting research area; VANET a mobile considered as special case (MANET). Similar to MANET, characterized autonomous and self-configured wireless network. However, has very dynamic topology, large variable size, constrained mobility; these characteristics led need for efficient routing resource saving protocols, fit with different environments. These differences render traditional MANET's protocols unsuitable VANET. The aim this work give survey VANETs mechanisms, paper gives overview Vehicular networks (VANETs) existing protocols; mainly it focused on vehicle (V2V) communication protocols. also represents general outlines goals VANETs, investigates schemes that have been developed well providing classifications (focusing two classification forms), summarized comparisons between classes in context their methodologies used, strengths, limitations each class scheme compared other classes. Finally, extracts current trends challenges mechanisms VANETs.
