A virtual P-Persistent bandwidth partitioning manager for VANET's broadcast channel

Different message urgencies leads to different bandwidth treatments in dense VANETs. Safety messages have the utmost importance in VANETs, therefore, it must have the highest assurance of delivery. However, due to the limited bandwidth of dense VANETs, safety messages could be rejected. This research is intended to formulate a policy to achieve minimal blocking of safety messages while keeping non-safety-related messages such as comfort messages not heavily penalized. Through virtually partitioned VANET's bandwidth and by applying P-Persistent scheme to reduce message congestion, an improved performance of message dissemination in VANETs can be achieved.
