- Background/Objectives: WAVE is the core technology of the research including smart car and autonomous driving. In this paper, we designed WAVE software architecture, and developed WAVE management functions. Methods/Statistical analysis: IEEE 1609 Standard provides guideline about functions that are necessary for WAVE service. WAVE is designed on IEEE 802.11p WLAN, with multi-channel operation. But it has been mentioned that the area of implementation is left to the developer's discretion. In order to support WAVE service, we must consider the structure of interworking between other layers as well as implementation of these capabilities. Findings: For development of WAVE SW, we suggest main structure based on layer-queue. In WAVE standard, MAC layer has a transmit queue corresponding to the channel identifier and priority. However, there is not mentioned about an intermediate layer structure for transmission data and management packets. Because of bypassing of packets in intermediate layer, workload has been concentrated into high layer or MAC layer. Along with suggested layer-queue, we separate a module independently to handle inbound and outbound higher layer data along. Improvements/Applications: The processing by layer-queue can be distributed the workload and delay of MAC SW.
