The automation of today's large-scale industrial systems relies on the operation of distributed controller devices that perform local computations and exchange information via communication networks. The subject of this paper is the development of a family of shared-medium industrial communication protocols that support the transmission of real-time (RT) and nonreal-time (nRT) data among distributed controller devices. Different from existing protocols, we suggest to incorporate information that is available from the control application in the protocol definition. As a result, our protocols dynamically change the bandwidth allocation on the shared medium according to the instantaneous communication requirements while ensuring hard RT guarantees. Following the recent developments in industrial automation, our protocols can be realized as software layers on top of low-cost conventional Ethernet.

Cooperative relaying schemes for narrow-band frequency hopping wireless ad hoc networks Yenihayat, Güven; Onat, Furuzan Atay; Kolaǧasioǧlu, Ertuǧrul; Yılmaz, Ali Özgür (2011-08-29) Cooperative relaying is a promising technique for improving the performance of weak communication links in wireless networks by exploiting spatial diversity induced by relay transmissions. This paper considers cooperative relaying schemes for a narrow- band frequency hopping system. A novel hybrid relaying scheme called opportunistic hybrid relaying, which is specifically designed for this system, is presented. Unlike most relaying schemes in the literature, opportunistic hybrid relaying uses bandwidth effi...
Implementing and evaluating the coordination layer andtime-synchronization of a new protocol for industrial communication networks Turan, Ulaş; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2011) Currently automation components of large-scale industrial systems are realized with distributed controller devices that use local sensor/actuator events and exchange shared events with communication networks. Fast paced improvement of Ethernet provoked its usage in industrial communication networks. The incompatibility of standard Ethernet protocol with the real-time requirements encouraged industry and academic researchers to provide a resolution for this problem. However, the existing solutions in the lit...
Direction of Arrival estimation by using Alternating Direction Method of Multipliers in distributed sensor array networks Nurbaş, Ekin; Tuncer, Temel Engin; Onat, Emrah; Department of Electrical and Electronics Engineering (2022-8-26) In recent years, developments in microprocessor and wireless communication technologies have benefited a variety of distributed sensor network applications, including array signal processing. Researchers have been investigating distributed implementations of array signal processing algorithms, such as Direction of Arrival Estimation, for a variety of applications. Performance and practical implementations of those algorithms are affected by a variety of factors, such as inter-array phase and frequency match...
Simulation and performance evaluation of a distributed real-time communication protocol for industrial embedded systems Aybar, Güray; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2011) The Dynamic Distributed Dependable Real-Time Industrial communication Protocol (D3RIP) provides service guarantees for Real-Time traffic and integrates the dynamically changing requirements of automation applications in their operation to efficiently utilize the resources. The protocol dynamically allocates the network resources according to the respective system state. To this end, the protocol architecture consists of an Interface Layer that provides time-slotted operation and a Coordination Layer that as...
Dependability design for distributed real-time systems with broadcast communication / Kartal, Yusuf Bora; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2014) The operation of distributed systems relies on the timely exchange of message data via dependable communication networks. Previous works suggest hardware redundancy for potential faults in the underlying network infrastructure to achieve dependability. However, software faults and faults that cannot be resolved on the hardware level are not considered in the existing literature. This work proposes a new method for software fault-tolerant communication in distributed real-time systems with communication netw...
