Voting with ghosts

Abstract
A mechanism called voting with ghosts (VWG) is proposed for maintaining consistency of replicated data. VWG is an improvement of the weighted voting (WV) algorithm; it performs as well as the available copies (AC) algorithm, but unlike AC, works correctly in the face of network partitioning. A detailed description of the VWG method is given, and it is analyzed in the presence of node crashes and network partitions. Its performance is compared with that of WV and AC
