As the complexity of vehicular distributed systems increases rapidly, several hundreds of devices are being placed in a modern automotive system. With the increase in wiring cables connecting these devices, the weight of a vehicle increases significantly and degrades the fuel efficiency during driving. In order to reduce the wiring weight, wireless communication has been introduced to replace wiring cables between some devices. However, the extra energy consumption and the transmission delay due to wireless communication need to be considered because they may result in frequent maintenance (e.g., recharging of batteries) and deadline violation, respectively. In this paper, we propose an intravehicle network routing algorithm to simultaneously minimize the wiring weight and the wireless transmit power while considering the transmission delay in automotive systems. Experimental results show that the proposed method can effectively minimize the wiring weight and the wireless transmit power and satisfy other design constraints.
