The increasing trend of wireless sensor communications in automotive Intra-Vehicular Network (IVN) has imposed a great pressure on wireless link capacity. This is particularly highlighted by a massive number of automotive sensor devices competing for the same transmission channel, which results in significant packet congestion and delay. As an effort to mitigate this situation, this paper presents a comparative performance study of two existing medium access control (MAC) strategies, namely history-based MAC and priority-based MAC, in handling the traffic growth in the IVN. History-based MAC utilizes latest successful transmission parameters for the current transmission attempt whereas Priority-based MAC regulates each node's communication timing. Our numerical simulation results demonstrate a trade-off between these two schemes in terms of packet queuing delay and delivery rate. The Priority-based scheme, in average, suffers from a high transmission delay due to prioritization, but achieves a high packet delivery rate. On the other hand, the History-based scheme attains a low queuing delay at the expense of less successful transmission attempts per unit time. © 2018 IEEE.
