Abstract

Collision-free transmission is important for reliable and delay-bounded wireless communication, which is required by many safety-related applications in vehicular ad-hoc networks (VANETs). However, with the increase of the vehicle node density, the channel contention collision of IEEE 802.11p known as the media access control (MAC) protocol standard for VANETs increases as well. Aiming at this problem, we propose a context-aware MAC protocol for VANETs with the basic idea of ensuring only one vehicle node access the channel initiatively while others conceal their contend intentions. According to the context message, we use the hamming competing network to decide which node will access the channel. Simulation results show that the proposed protocol has a considerably low collision probability and high transmission reliability while keeping a low access delay even in high dense scenario.
