Disconnection Tolerance in Reliable Timeout Based Commit Protocol

Abstract

The transaction processing on the mobile network may lead to disconnection due to poor bandwidth. To deploy traditional database applications into the mobile networks the transactions are to be executed consistently without hindrance of blocking. In this paper, the proposal is made to handle the transactions efficiently despite the frequent disconnections of the wireless network. With the use of log at MH & also at FH, it is possible to process transactions locally during disconnection & reflect updates after getting reconnected. This may lead to non-blocking situations, reducing the message costs, & enhancing the throughput. The simulation results specify the performance analysis metrics.
