Systematic message schedule construction for time-triggered CAN

2007-11-01
The most widely used standard for in-vehicle communication networks that interconnect electronic control units is the controller area network (CAN). However, the event-triggered architecture of CAN introduces several issues, such as predictability, signal jitter, and reliability. Different time-triggered networks. are being developed to address these issues. In this paper, we focus on time-triggered CAN (TTCAN), which achieves time-triggered behavior by implementing time-division multiple access on the existing CAN network standard. The main task is thus to construct a message schedule for a given set of messages while fulfilling certain performance criteria. To this end, we provide a formal framework for the construction of feasible message schedules in TTCAN networks by considering several performance metrics, such as bandwidth utilization and jitter, as well as the hardware constraints of the TTCAN controller specification.

Delay aware reliable transport in wireless sensor networks
Gungor, Vehbi C.; Akan, Oezguer B. (Wiley, 2007-10-01)
Wireless sensor networks (WSN) are event-based systems that rely on the collective effort of several sensor nodes. Reliable event detection at the sink is based on collective information provided by the sensor nodes and not on any individual sensor data. Hence, conventional end-to-end reliability definitions and solutions are inapplicable in the WSN regime and would only lead to a waste of scarce sensor resources. Moreover, the reliability objective of WSN must be achieved within a certain real-time delay b...
Message Scheduling for the FlexRay Protocol: The Dynamic Segment
Schmidt, Şenan Ece; Schmidt, Klaus Verner (Institute of Electrical and Electronics Engineers (IEEE), 2009-06-01)
The FlexRay communication protocol is expected to be the de facto standard for high-speed, in-vehicle communication. In this paper, we formally investigate the scheduling problem for the dynamic segment (DS) of FlexRay. We take the bounds on the generation times and the timing requirements of the signals into consideration to propose a reservation-based scheduling approach that preserves the flexible medium access of the DS. To obtain efficient schedules, we formulate a nonlinear integer program- ming probl...
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...
The performance and efficiency of envelope elimination and restoration transmitters for future multiple-input multiple-output wireless local area networks
Nesimoglu, T.; Parker, S. C. J.; Morris, K. A.; McGeehan, J. P. (Institution of Engineering and Technology (IET), 2008-03-01)
The inefficiency of contemporary power amplifiers ( PAs), when operating in their linear region, is a major obstacle to mobile operation of wireless local area networks ( WLANs) based on IEEE 802.11n. Therefore the use of more efficient envelope elimination and restoration ( EER) transmitter architectures is considered. In addition to high efficiency it is also necessary to satisfy the spectral mask and achieve satisfactory link- level performance. Link- level simulations of a contemporary WLAN PA show that...
Wireless Passive Sensor Networks
Akan, Ozgur B.; Isik, M. Talha; Baykal, Buyurman (Institute of Electrical and Electronics Engineers (IEEE), 2009-08-01)
The primary challenge in wireless sensor network deployment is the limited network lifetime due to finite-capacity batteries. Hence, the vast majority of research efforts thus far have focused on the development of energy-efficient communication and computing mechanisms for WSNs. In this article a fundamentally different approach and hence completely new WSN paradigm, the wireless passive sensor network, is introduced. The objective of the WPSN is to eliminate the limitation on system lifetime of the WSN. I...
