IEEE 1609.4 for safety and non-safety messages dissemination in VANET

A recent paper by Dr Ali Al-Sherbaz in partnership with  College of Information Engineering, Al-Nahrain University, Baghdad, Iraq looks at a VANET protocol for safety and non-safety message dissemination.

 The IEEE 1609.4 was developed to support multi-channel operation and channel switching procedure in order to provide both safety and non-safety vehicular applications. However, this protocol has some drawback because it does not make efficient usage of channel bandwidth resources for single radio WAVE devices and suffer from high bounded delay and lost packet especially for large-scale networks in terms of the number of active nodes. This paper evaluates IEEE 1609.4 multi-channel protocol performance for safety and non-safety application and compare it with the IEEE 802.11p single channel protocol. Multi-channel and single- channel protocols are analyzed in different environments to investigate their performance. By relying on a realistic dataset and using OMNeT++ simulation tool as network simulator, SUMO as traffic simulator and coupling them by employing Veins framework. Performance evaluation results show that the delay of single- channel protocol IEEE 802.11p has been degraded 36% compared with multi-channel protocol.
