摘要：The applications of VANETs falls into two categories namely safety application (event-driven applications) and non-safety application (periodic applications). These both categories coexist in the network operation mode proposed for DSRC. High priority must be given to safety messages as they contain critical information. The proper estimation of network traffic is highly important in Vehicular Ad Hoc Networks (VANETs) as they are expected to exchange high-priority critical messages. In reality, the network most of the time will handle low-priority traffic and in emergency situation will have to transfer high-priority traffic also. In this paper, performance evaluations of safety message dissemination in VANETs in Vehicle-to-Vehicle communication (V2V) are considered. The vehicles which are considered as nodes in VANET communicate or exchange messages with each other, which is referred to as V2V or Inter-Vehicle Communication (IVC). V2V communication is implemented through Dedicated Short Range Communication (DSRC) protocol. The main advantage of the V2V communication with DSRC will be decreased delay and efficient broadcasting of safety messages to far away nodes as possible. An adaptive algorithm (AMBA) is introduced to increase the system reliability in terms of the probability of packet’s successful reception and delay of emergency messages in a harsh vehicular environment.
