Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If connectionless transmission is used in existing vehicle-to-x systems, then system simplicity is maintained, but data rates, reliability, and latency performance deteriorate
Solution Approach 1:
The communication protocol is segmented into distinct connection establishment phase and data transmission phase. The connection establishment phase handles device discovery, authentication, and resource allocation, while the data transmission phase utilizes the established connection for efficient communication. This segmentation allows the system to achieve high data rates through connection-oriented transmission while managing complexity through phase separation.
Solution Approach 2:
The system performs preliminary actions during the connection establishment phase, including device discovery, capability negotiation, security authentication, and resource allocation. These preliminary actions are completed before actual data transmission begins, allowing the subsequent data transmission phase to operate at optimized speeds without the overhead of repeated connection establishment, thereby achieving higher data rates and lower latency.
2Reliability
If connectionless transmission is used, then implementation simplicity is maintained, but reliability and latency requirements for 5G deteriorate
Solution Approach 1:
The connection-oriented protocol incorporates feedback mechanisms that enable physical layer feedback and quality of service monitoring. The system can receive acknowledgment signals and quality metrics from the receiving device, allowing for real-time adjustment of transmission parameters, retransmission of lost packets, and optimization of resource allocation. This feedback loop significantly improves communication reliability while the established connection reduces overall protocol overhead compared to repeated connectionless handshakes.
3Productivity
If connectionless transmission is used, then system simplicity is maintained, but processing overhead increases
Solution Approach 1:
Once a connection is established, the system maintains continuous communication through the allocated resources without requiring repeated connection establishment procedures. The pre-established connection allows for continuous data transmission with minimal interruption, eliminating the processing overhead associated with multiple connectionless handshakes and resource allocation requests. This continuity significantly improves communication efficiency and reduces processing overhead for subsequent data transfers.
