Commit Protocol

An atomic commit protocol can cause long-term locking of databases if the coordinator crashes or becomes disconnected from the network. In this paper we describe how to eliminate the coordinator. This decentralized, cooperative atomic commit protocol piggybacks transaction statuses of all transaction participants onto tokens which are passed among the participants. Each participant uses the information in the tokens to make a decision of when to go to the next state of a three-phase commit protocol. Transactions can progress to ensure a uniform agreement on success or failure, even if the network is partitioned or nodes temporarily crash.

Atomic Commit

In this paper, the authors present a probabilistic model to evaluate the reliability of the atomic commit for distributed transactions in mobile ad-hoc networks (MANETs). This model covers arbitrary MANET scenarios as well as strict and semantic transaction models. The authors evaluate the approach to integrate a backup coordinator to reduce blocking risks. For the purpose of showing an example of a MANET scenario, the authors illustrate how the considered blocking probability is very low.
