Performance Evaluation of Multi-Channel Operation IEEE 1609.4 Based on Multi-hop Dissemination
The multichannel operations IEEE 1609.4 are an emerging standard which support the co-existence of safety (CCH Channel) and non-safety (SCH Channel) message application in vehicular networks. This strictly concerns on the transmission slot synchronization of CCH/SCH based on Wireless Access in Vehicular Environments (WAVE) to achieve QoS requirements (i.e. to improve packet delivery ratio and reduce delay). In this paper, the authors study the performance of the IEEE 1069.4 based on multi-hop dissemination compared with the single-hop dissemination in vehicular network to get SCH and CCH channel performance. Their work also compared multi-hop with single-hop dissemination based on the performance based on the IEEE 802.11p Enhanced Distributed Channel Access function (EDCA) standard in a vehicular environment to get packet delivery ratio performance in vehicular networks.
