Improving the Quality of Service in the Vanet By Detecting and Removing Unused Messages

In the past, traffic safety was addressed by traffic awareness and passive safety measures like solid chassis,seat belts, air bags and etc. thanks to the ongoing progresses in the concept of vehicular ad hoc networks (vanet),propitious conditions for finding efficient solutions for traffic safety are meeting. safety messaging is the mostimportant aspect of vanets where the passive safety (accident readiness) in vehicles was reinforced with the idea ofactive safety (accident prevention). in safety messaging vehicles message each other over wireless media and updateeach other on traffic conditions and hazards. owing to the importance of the qos in safety messaging, manyresearchers have focused on this topic. earlier related works have scrutinized the aspect of increasing the service rateby changing the properties and parameters of scheduler algorithms but this paper with a new look at the issue ofquality of service tries to increase the performance of vanet by removing the useless or unused packets.
