Although previous studies have effectively improved fault tolerance by focusing on various aspects of this area, previous methods are ineffective in ensuring the stability and accuracy of data exchange in the event of failure. The existence of this problem shows the need to propose a new method that can guarantee the stability and accuracy of data exchange to guarantee the stability of network performance in case of failure. To achieve this, this research introduced a method called FTRTA, which is based on the development of the RPL protocol and data distribution techniques. Distribution techniques are effective in improving load balancing and fault tolerance of network traffic. The FTRTA was developed based on this technique and in three operational steps. Firstly, the situation of the network nodes is evaluated and analyzed in the same way as when sending DIO messages. In the second step, the network communication graph is created. Finally, in the third step, data transmission is based on a distribution technique to ensure fault tolerance. The simulation results using Cooja software show the high performance of FTRTA in ensuring the stability and accuracy of data exchange, improving factors such as successful receptions and network throughput compared to similar studies.

These applications which need to work non-stop and continuos for a long period are prone to errors. Therefore, they are required to be fault tolerant as much as possible. Most of fault-tolerant methods provided for multi-agent systems are based on replicating the number of agents which leads to more complexity in these systems. In this paper we used task replication along with increasing numbers of agents in MaSE methodology to have a reliable architecture with high fault tolerante capability for multi-agent systems.

When the dimensions of the components decrease, the sensitivity of the circuit increases and the quantum circuits become more vulnerable to the occurrence of defects and radiation in the environment. The two major gates in this technology are inverter and majority gates, and most circuits are built based on these two gates. This paper aimed to design a seven-input majority gate in quantum-dot cellular automata by imposing low overhead on the circuit. Using a majority gate with more inputs reduces cell count, latency, and complexity in the QCA circuit. However, perhaps the need to use the seven-input gate is not yet felt we then design and implement a number of logic circuits. A new 7-input majority gate is designed in this paper, with 19 cells. The proposed structure is single-layer with an occupied area of 24564 nm2 that produces the correct output in one clock phase, then a four-input AND gate, a four-input OR gate, a two-input XOR gate, a two-input XNOR, a three-input XOR gate and a full adder are implemented using the designed seven-input gate. Including all multi-bit full adders, using the proposed seven-input gate. The proposed full adder is designed by the seven-input majority gate proposed and a fault-tolerant three-input majority gate. Therefore, it can be said that the designed full adder is somewhat tolerable, that means, it is somewhat tolerable against the fault that occur in this technology. QCAPro software is used to analyze the energy consumption of the recommended structure. Then, the circuit performance is evaluated using QCADesigner 2.0.3 simulator software for quantum-dot cellular automata. Manuscript profile -

It states different ways in which combination of faulty components result in an undesired event in the system. Being used in phases such as designing and exploiting industrial systems, and the designers able to evaluate the dependability attributes such as reliability, MTTF and sensitivity. In addition, in the mentioned ability, the fault tree is a systematic method for finding systems bottlenecks and weakness point. In spite of its extensive use in evaluating the reliability of systems, fault tree is rarely used in calculating sensitivity. In the last decade, few researches has been conducted in this field, however these methods are not applicable to large scale systems and are not systematic. This paper provides a systematic method for evaluating system sensitivity through fault tree. Then, it introduces sensitivity of NMR architecture as one of the common structures of fault tolerance which is used for enhancing systems’ reliability, safety and availability in industry. This article presents a comprehensive and parameterized formula for NMR structure's sensitivity. The presented method can be a great help for designing and exploiting reliable systems engineers in systematic and instant calculation of sensitivity by means of fault tree. Manuscript profile -
