The concept of Internet of Things (IoT) (i.e., large number of nodes are interconnected each others) can be utilized in vehicle, since the number of sensor nodes has increased significantly due to the uplifting demand of various safety and convenience applications. The controller area network is a widespread system of communication between sensor nodes inside a vehicle with wired connections, however, the wired architecture is not scalable and flexible due to the complex architecture inside the vehicle. Therefore, there is an increasing level of appeal to design a reliable system in which the wired connections to the sensor nodes are replaced with wireless links. In this paper, we design a wireless sensor network for reliable intra-vehicular communications based on concept of IoT. Firstly, we study the design of single link between a base station and a sensor node. Then we design a complete scenario, where more sensor nodes transmit their packets, to generalize the design for a larger intra-vehicle wireless sensor network. For achieving reliable communications, we define two different levels of reliability: one is single link reliability and other is network reliability. Finally, the performance is evaluated in terms of network reliability. The simulation results assist to design a robust system for intra-vehicular communications.
