The IEEE 1609.4 standard for Vehicular ad hoc network has been proposed to enhance the IEEE 802.11p MAC to support multi-channel operation. Multi-channel operation separate safety and non-safety related applications on a different channel. The vehicles must periodically switch between control channel and service channel to concurrently exchange the safety and non-safety related messages so that the problem of contention between applications can be avoided. In this paper, the authors measure the performance of both safety and non-safety related applications on multi-channel operations and compared to the single-channel operation.
