A Comparison of Communication Mechanisms in Vehicular Edge Computing
summary
End-to-end prototype supports Wi‑Fi (router), LTE (USRP B210 + srsLTE with EPC/eNodeB), and DSRC (small‑car OBU/RSU, TCP gateway) and runs ROS message flows for raw pose, BSM and image. Measured end‑to‑end latency, power and system overhead: LTE gives lowest latency for tiny BSM/ping bytes, Wi‑Fi gives best throughput for image frames, DSRC yields the most stable low latency under mobility. Power for LTE/DSRC >8–12 W and system overhead for srsLTE/ROS consumes ~1.5–1.6 GB and high CPU.
