Abstract
- Peer-to-peer (P2P) file sharing systems often replicate files to multiple nodes. File replication is beneficial in the sense that it can achieve good query latency, load balance, and reliability. However, it introduces another problem of maintaining mutual consistency among replica when a file is updated. The new file has to be propagated to all of its replica. In this paper, we propose an update propagation algorithm for P2P file sharing over wireless mobile networks (MONET). Compared to the previous algorithms proposed in wired P2P file sharing systems, our algorithm has low communication overhead. It also guarantees safe delivery of updates even when the underlying network is unreliable. This means that our algorithm is well matched to the characteristics of MONET such as limited battery power of mobile nodes, lower network reliability, and frequent disconnection of mobile nodes.
