The controller area network (CAN) bus, the prevailing standard for in-vehicle
networking (IVN), has been used for more than four decades, despite its simple
architecture, to establish communications between electronic control units
(ECUs). Weight, maintenance overheads, improved flexibility, and wiring
complexity escalate as the quantity of ECUs rises, especially for high-demand
autonomous vehicles (AVs). The primary objective of this study is to examine and
discuss the significant challenges that arise during the migration from a wired
CAN to a wireless CAN (WCAN). Suggested remedies include changing the
configuration of the conventional ECU, creating a hidden wireless communication
domain for each AV, and developing a plan to counteract the jamming signals. The
simulation of the proposed WCAN was done using MATLAB and validated using OPNET
analysis. The results showed that the packet loss of the eavesdropping
electronic control unit ranged from 63% to 100%. Anti-jamming results show that
when packet loss reaches 2% for a continuous period of time of 0.01 sec, the
passive channel is automatically activated, ensuring secure data
transmission.
