It is well known that consensus algorithms are fundamental building blocks for fault tolerant distributed systems, including distributed collaborative systems. In the literature of consensus, many algorithms were proposed to solve this problem in different system models but not a lot of efforts were made to analyze their performance. This paper compares the(More)
The consensus problem has become a key issue in the field of collaborative telemedicine systems because of the need to guarantee the consistency of shared data. In this paper, we focus on the performance of consensus algorithms. First, we studied, in the literature, the most well-known algorithms in the domain. Experiments on these algorithms allowed us to(More)
It is well known that consensus algorithms are fundamental building blocks for fault tolerant distributed systems. In the literature of consensus, many algorithms have been proposed to solve this problem in different system models but few attempts have been made to analyze their performance. In this paper we present a new leader-based consensus algorithm(More)
