Congestion control framework for disseminating safety messages in vehicular Ad-Hoc networks (VANETs)

The purpose of this study is to propose a new congestion control framework for uni-priority of event-driven safety messages in VANETs. The uni-priority congestion is caused by the traffic of the same priority. Many of event-driven safety applications developed for VANETs is required real-time commun...
