Intra-Vehicle Network Routing Algorithm for Minimization of Wiring Weight and Wireless Transmit Power

Abstract

As the complexity of vehicular distributed systems increases rapidly several hundreds of devices (sensors actuators etc ) are being placed in a modern automotive system With the increase in wiring cables connecting these devices the weight of a car increases significantly which degrades the fuel efficiency in driving In order to reduce the weight of a car wireless communication has been introduced to replace wiring cables between some devices However the extra energy consumption for packet transmissions by wireless devices requires frequent maintenance e g recharging of batteries Moreover the latency is one of important factors in automotive systems and as the traffic safety directly rely on it we need to consider it seriously In this thesis we propose an intra-vehicle network routing algorithm to simultaneously minimize the wiring weight and the transmit power for wireless communication while considering the transmission latency in the automotive system Simulation results show that the proposed method can effectively minimize the wiring weight and the transmit power for wireless communication
