Abstract
Embodiments of the present disclosure are directed to vehicle communication systems, in particular, toward contention resolution on a shared medium in vehicle communication systems. The present disclosure can provide a modified version of the Institute of Electrical and Electronics Engineers (IEEE) 802.3 standard to handle physical layer (PHY), and data link layer's (DLL) media access control (MAC) of the wired communication links in the vehicle communication subsystem utilizing a shared medium and half-duplex mode. As a result, the modified MAC and PHY may provide fair access and deterministic latency for shared access to the medium of vehicle communication systems independent of the offered network load.
