High throughput performance of the Wireless Access in Vehicular Environment (WAVE) system can provide more capacity for future high density traffic, which is little considered in the ongoing IEEE 802.11p/P1609.4 defined WAVE Medium Access Control (MAC) protocol. To achieve this goal, we propose a novel multi-channel MAC protocol that can use a dynamic time boundary instead of fixed boundary to separate...
In this paper, we propose an algorithm for joint adaptation of transmission power and contention window to improve the performance of vehicular network in a cross layer approach. The high mobility of vehicles in vehicular communication results in the change in topology of the Vehicular Ad-hoc Network (VANET) dynamically, and the communication link between two vehicles might remain active only for...
When the volume of traffic on a roadway is so high such as traffic jam, medium access control (MAC) protocols in inter-vehicle communication (IVC) systems do not work well. The primary reason is the huge amount of communication traffic, which could be resolved by conventional transmission cycle control (TCC) schemes. However, when using TCC schemes, the failure of packet transmission extends the communication...
