The response time distribution (RTD) for messages on the controller area network (CAN) represents the probability of experiencing each possible response time. The existing literature suggests to use the RTD for the design of real-time applications based on CAN. This paper shows that the RTD does not capture the response time behavior on CAN well due to gradual clock drifts among CAN nodes. Instead

Computation of Response Time Distributions for Messages on the Controller Area Network Batur, Ahmet; Schmidt, Şenan Ece; Schmidt, Klaus Verner (2018-08-23) The response time of messages is an important parameter for the design of in-vehicle networks based on the controller area network (CAN). The message transmission on CAN is affected by several non-deterministic factors such as stuff bits that are added to CAN frames depending on the message payload or changing phases among the asynchronous CAN nodes because of clock drifts. The resulting probabilistic nature of message response times on CAN is captured by the response time distribution (RTD) that quantifies...
Improved load distribution for controller area network Batur, Ahmet; Schmidt, Şenan Ece; Schmidt, Klaus Verner (2017-06-29) The main requirement for the design of the controller are network (CAN) is to guarantee that each message response time is smaller than their specified deadline. In practical in-vehicle applications, messages on CAN are released with offsets in order to avoid message bursts that lead to undesirably large response times. In this paper, new algorithms for the choice of suitable message offsets are developed and it is shown that these algorithms outperform existing algorithms.
Clock synchronization and weak TDMA for CAN FD: Implementation and evaluation Demirel, İsmet Onur; Schmidt, Şenan Ece; Schmidt, Klaus Verner; Department of Electrical and Electronics Engineering (2022-12-27) The Controller Area Network (CAN) is the most widespread in-vehicle communication protocol. Although CAN has been used for many decades, there are very recent software-based enhancements that enable accurate clock synchronization and time-slotted medium access on CAN, denoted as weak time division multiple access (WTDMA), for deterministic bus access. In addition, there are recent updates to the CAN hardware such as CAN with flexible data rate (CAN FD) in order to both increase the available bit rate and th...
Offset assignment on controller area network: Improved algorithms and computational evaluation Batur, Ahmet; Schmidt, Klaus Verner; Schmidt, Şenan Ece (2017-07-26) The basic requirement for the design of the Controller Area Network (CAN) for in-vehicle communication is to guarantee that the worst-case response time (WCRT) of each message is smaller than their specified deadline. In addition, it is desired to achieve small WCRTs that leave sufficient slack to the message deadline.
Evaluation of Terahertz Channel in Data Centers MOLLAHASANİ, Shahram; Onur, Ertan (2016-04-29) Designing data center network topologies with the objective of minimizing cost, increasing bisection bandwidth and decreasing latency is a difficult problem. The solutions in the literature mainly concentrate on wired networks and minimizing wiring costs thereof. Only a few proposals address the benefit of employing wireless communications in data centers due to spectrum and bandwidth limitations of current wireless communication technologies. By using terahertz communication in a data center as a complemen...
