Analysis of transaction throughput in P2P environments

In recent years P2P systems have gained tremendous popularity. Support of a transaction processing facility in P2P systems would provide databases at a low cost. Extending distributed database algorithms such as 2PC and ROWA to P2P environments might not provide the best performance because the P2P systems are characterized by high site failure rates and an unpredictable network topology. The choice of algorithms in building P2PDB is difficult because of the lack of information about the performance of database algorithms in P2P environments. This thesis analyzes the performance of one such algorithm, the epidemic algorithm against the performance of traditional database algorithms in simulated P2P environments.
