摘要: Reliability is one of the key requirements for inter-vehicle communication in order to improve safety road traffic. This paper describes difficulties communication. We focus on an analysis state-of-the art MAC protocol draft IEEE P802.11p and its limitations high load situations. For our we consider a particular scenario: An emergency vehicle approaching traffic jam. In simulation experiment, highlight that severe packet loss can occur. The reliable transmission range be reduced by up 90%. main reason this degradation interference caused transmissions other vehicles within study, at very end There, measure number packets per second are successfully received from vehicle. observation only small fraction warning lead time remains which will also reduce driver react information
