“…FlexRay is an automotive network communication protocol developed by the FlexRay Consortium to govern on-board automotive computing. It is discussed in several research efforts [46,47,48]. The Local Interconnect Network (LIN) bus is a serial communication protocol used to connect components in vehicles.…”

We present the Smart Surface Network (SSN), a hardware and software platform designed for dense sensing. Sensor nodes connected to the SSN communicate using a serial bus integrated within a mountable physical surface. The hardware architecture and bus access and communication mechanisms are implemented in a self-stabilizing manner, providing robust handling of unannounced arrivals and departures of network devices. An associated API supports a peer-to-peer communication paradigm, providing access to the physical, data link, and application layers of the bus. In this paper, we describe the SSN hardware architecture and present the bus access and peer discovery algorithms. We also discuss the design of the API and describe experimental results characterizing the fairness of the bus algorithm, the efficiency of the peer discovery algorithm, and the performance of the SSN system under varying load conditions.

“…If the bus is pulled low, the search is not complete, so the device will wait through the remainder of the ID read cycle, synchronizing itself with each bit. If the bus is not pulled low, the search is complete, and the device prepares to accept the next command (Listing 3, lines [38][39][40][41][42][43][44][45][46][47].…”

Data Distribution Service (DDS) middleware has become one of the best solutions for real-time distributed industrial systems. An interesting innovation would be the use of the DDS middleware on top of Ethernet networks to enhance the performances of automobile applications. In this paper, we will introduce the use of DDS on top of Ethernet networks and propose as a testing application an extended SAE (Society of Automotive Engineers) benchmark. The main aim is to be able to calculate the worst case response time (WCRT) based on a scheduling model, and using it as a metric to evaluate the respected of DDS real-time QoS (Quality of Service). The results obtained by using Ethernet are compared to the results found using FlexRay.
