A novel probabilistic bit voter using genetic algorithm for fault-tolerant systems


Manizheh Mirsaeidi and Abbas Karimi

Fault-tolerant systems are systems that can continue their operations even in the case of an error. These systems are used in the real-time systems, embedded business systems, e-commerce, transport systems (including rail, air and car), nuclear energy, electronic Ad-hoc system, space and military networks and industrial environments. Voting algorithms[13] are used in a wide area of control systems from real-time and safety-critical control systems to pattern recognition, image processing and human organization systems in order to arbitrating among redundant results of processing in redundant hardware modules or software versions .Bit voting algorithm is a voting algorithm used for fault-tolerant control systems. In this paper, a new bit voting based on a probabilistic algorithm is proposed. Some of voters do not provide good availability play an important role in proper implementation of the systems. Experimental results show that the proposed voter improve availability considerably.

Keywords: Fault-tolerant systems, bit voting algorithms, probabilistic voting algorithm, genetic algorithms.
