Two-Phase Majority Decision Scheme Using Time-Stamps
Yuzuru Maya · 2013
Mission critical files are shared through networks, making file manipulation a serious problem. In a system consisting of a main-node and sub-nodes, I propose a two-phase majority decision scheme using time-stamps as an identifier in order to solve this problems. In the first phase, the main-node checks the time stamps of its own files and files them in sub-nodes. If the results are effective, the main-node sets the files as members of the majority decision scheme. In the second phase, the main-node runs the majority decision scheme from the selected files. I evaluated the reliability and MTBF of the conventional and proposed majority decision scheme. I also show that the reliability and MTBF of the proposed scheme is 2-4 times of that of conventional scheme and that the proposed scheme is suitable for multi-faults of files.
