An Efficient TDMA Synchronization Approach for Distributed Embedded Systems
نویسندگان
چکیده
A desired attribute in safety critical embedded real-time systems is a system time/event synchronization capability on which predictable communication can be established. Focusing on bus-based communication protocols, we present a novel, efficient, and low-cost synchronization approach for TDMA environments. This approach utilizes information about each node’s unique message lengths to achieve synchronization. We present a fault-tolerant initial synchronization protocol with a bounded start-up time. The protocol avoids start-up collisions by postponing retries after a collision. We also present a resynchronization strategy that incorporates recovering nodes into

Improving LoRaWAN Performance Using Reservation ALOHA
LoRaWAN is one of the new and updated standards for IoT applications. However, the expected high density of peripheral devices for each gateway, and the absence of an operative synchronization mechanism between the gateway and peripherals, all of which challenges the networks scalability. In this paper, we propose to normalize the communication of LoRaWAN networks using a Reservation-ALOHA (R-A...
متن کاملEfficient and Reliable Communication in Distributed Embedded Systems
The use of distributed computing elements has grown in the embedded systems arena, consequently the use of shared communication media linking these computers has garnered increasing attention. Two prominent and contemporary media sharing approaches include variations of controlled and contention based media access paradigms, with the timetriggered (TT) and the event-triggered (ET) approaches, r...
متن کاملLinear matrix inequality approach for synchronization of chaotic fuzzy cellular neural networks with discrete and unbounded distributed delays based on sampled-data control
In this paper, linear matrix inequality (LMI) approach for synchronization of chaotic fuzzy cellular neural networks (FCNNs) with discrete and unbounded distributed delays based on sampled-data controlis investigated. Lyapunov-Krasovskii functional combining with the input delay approach as well as the free-weighting matrix approach are employed to derive several sufficient criteria in terms of...
متن کاملSafety Evaluation of Critical Applications Distributed on TDMA-Based Networks
Critical embedded systems have to provide a high level of dependability. In automotive domain, for example, TDMA protocols are largely recommended because of their deterministic behavior. Nevertheless, under the transient environmental perturbations, the loss of communication cycles may occur with a certain probability and, consequently, the system may fail. This paper analyzes the impact of th...
متن کاملEnhancing Real-Time Event Service for Synchronization in Object-Oriented Distributed Systems
Distributed object computing middleware such as CORBA, RMI, and DCOM have gained wide acceptance and has shielded programmers from many tedious and error-prone aspects of distributed programming. In particular, CORBA Event Service has been used extensively in embedded systems. In this paper, we propose an aspect oriented approach to develop synchronization code for distributed systems that use ...
